106  Camaro Research Group Discussion / Restoration / "68 Rear bumper mounting trouble.....hole to hole check dimensions available? on: March 28, 2013, 07:35:56 PM
I had my original '68 rear bumper straightened and re-chromed. I have reproduction 1/4 panels and tail panel. I also have reproduction CHQ bumper brackets with the exception of the center bracket which is the original one to the car.

I am having trouble making the bumper fit right........ I can get it on the car but cannot get the driver side corner bracket hole to line up with the hole in the quarter panel. Also, I haven't tried it yet but it seems it would take a lot of bolt torquing to pull the two brackets that are between the corner brackets and the center bracket tight to the body

I guess the problem could be anywhere.....1/4 panel, tailpanel, brackets or the bumper itself...........Or maybe I am not doing it the right way.

Is there a correct sequence or procedure when mounting the rear bumper?.. ..Maybe a different way would give different results.......Should the brackets go on the bumper first? (how loose or tight?) and then the brackets to the body? Or the brackets on the body first (how loose or tight?) and then the bumper to the brackets? Or a combination of both? What should you tighten first and how hard should you tighten everything?

I also want to make sure the bumper was straightened correctly. The shop that straightened it said they had some sort of guide that they used to make sure everything was right.

Does anyone know of any published "check" dimensions for a '68 rear bumper? To be able to check if all the mounting holes are in correct relation to each other. To be able to prove that the chrome shop did it right.

Thanks.......Dave

The tail panel to trunk lid alignment seems to be pretty good from what my amateur eyes can tell. After looking at your photos of the three different tail panels, I'd  have to say mine look more the GM and AMD than the other. I don't know what brand was used by the shop that did the work.

Scott, thanks for the reply. Yes....repro quarters too! When you say the 1/4 inch is divided by two, I assume you mean you would tilt the bezel so that you have an 1/8 inch gap at oppsite corners instead of the whole 1/4 inch at one corner.  I am not sure what you mean when you say body work cannot be done from a screen, though. When you say you can make multiple manipulations for a better fit, can you be more specific?

I am attaching a photo of my entire tail pan area. I really don't know how to tell a GM tail panel from one that's not. If it doesn't look like a GM, is that significant for anything other than correct appearance?

Thanks......Dave

By the way....does anyone know if I might be better off buying a set of CHQ bezels rather than using OER ones that were manufactured twelve years ago?

109  Camaro Research Group Discussion / Restoration / Re: '68 taillight bezels won't fit properly. on: March 24, 2013, 01:10:32 PM
Thanks for everyone's opinions and ideas.

I know that gaskets will fill gaps. I see some cars out there where the gasket will be squeezed down to nothing in one corner of the taillight bezel and a 1/4 inch thick on another corner. I don't think that looks so good. Is that the best you can hope for with reproduction parts?                       

I see other cars out there that seem to be an almost perfect fit all the way around with the gasket barely visible. Are these original  parts, better reproduction, or someone who just got lucky?

I wanted to see if my problem was the tail panel, the bezels, or both so I took a piece of wood cut it in the shape of the bezel, put a screw through it at each corner, and adjusted the screws so that the end of all four screws touched a flat surface at the same time. (the end of all four screws were in the same plane). The I put the screws up to the taillight openings and the new OER bezels to see what might be warped.







What I found with the taillight openings was that the top, outside corner on each opening was pulled in a 1/4 inch from the other three corners and that the OER bezels seem to be flat. (All four screws touch the corners of the bezel at the same time)

I guess my questions now are......Is this the correct shape of the tail panel and the bezels should have be manufactured to match?.......or is the tail panel warped and the bezels the correct shape?

I haven't tried this yet since I don't have gaskets yet......but if you crank down all the stud bolts and draw the bezel tight to the tail panel, are you going to notice distortion in the tail panel?

           Thanks,
           Dave
110  Camaro Research Group Discussion / Restoration / '68 taillight bezels won't fit properly. on: March 21, 2013, 09:51:06 PM
I am having trouble with the fitment of the taillight bezels on my '68. I have a reproduction tail panel and OER bezels that were bought new in 2001 and stored away until now. The studs on the taillight bezels fit the holes in the tail panel OK. The problem that the bezels do not sit tight to the tail panel at all four corners at the same time. Also, the curvature of the bezel from top to bottom does not match the curvature of the tail panel exactly.

No body work or metal shaping work has been done on the tail panel since it was installed. The worst side is the passenger side where, when three corners of the bezel touch the tail panel, the fourth corner is sticking out a 1/4 inch. (See the picture. Three corners are touching. You can see the shadow being cast by the lower , left hand corner that is up)

I am getting ready to send the car to the body shop for final body work and paint and this can't be left this way.

I am not sure if the the problem is the tail panel....the bezels.....or a combination of both.

Can anyone comment on these OER bezels that are unused but twelve years old now and if they were known to fit poorly?

Would I be better off with a new set of CHQ bezels which seem to have a good reputation?

Can a body man do anything with the tail panel for a better fit without warping it?

Any suggestions would be appreciated.


Thanks.......Dave

I am not meaning to hijack the thread but I have a question and JKZ27 might find the answer useful also. When Al Knoch restores a door panel, what parts of the original door panel remain and what is new. I have a '68 deluxe door panel which is made up of the heavy cardboard backing that has a 2 inch wide metal strip running across the top. I am assuming there is foam between the carboard backing and the vinyl covering.

112  Camaro Research Group Discussion / Restoration / Re: Vigilite Light Monitoring System Fiber Optic Cable on: February 21, 2013, 03:21:43 PM
Several years ago, I went to the junkyard and raided some fiber optic cable from some 70's or 80's Cadillacs. The cable used for the rear monitor of the Cadillacs was identical to that used in the  rear monitor of my '68 Camaro. I don't know if any of those Cadillacs exist in the junkyards anymore. The attached photo is of cable I took from the Cadillacs.

114  Camaro Research Group Discussion / Restoration / Body filler questions on: February 13, 2013, 06:00:00 PM
This is my first real use of body filler and I have some questions. Right now I am trying to do cosmetic work on parts that are sound but have pitting in them. My subframe, a-arms, front bumper brackets, and things like that.

1) I am trying to get the mix ratio of hardener right. I did some experimenting. The first two times, I added too much and it set up too fast. The third time, I had about three minutes to spread it before it started to set up. Is this about right or should I try less hardener. Is there a standard "working time" before set up that tells you your mix is right?

2) How long after you apply the filler should you wait till you start sanding.

3) How long should you let the filler dry before applying paint?

4) How long can you leave the filler exposed before you put paint on it? Will the filler start to absorb moisture if it sits exposed too long?.......and cause problems with the paint later?

5) If you wipe it with wax and grease remover before painting, is there a certain amount of time you should wait to let it completely evaporate out?

6) These parts were already sandblasted and epoxy primered. I am putting the body filler over the epoxy primer. I am going to use Eastwoods 2K Chassis Black for the final coat........should there be a primer between the body filler and the final coat.......and if so, what is recommended?

Thanks.............Dave
115  Camaro Research Group Discussion / Restoration / Moog tie rod end boots won't come off ! on: December 23, 2012, 08:56:33 PM
I have new Moog tie rod ends for my '68. I want to prime and paint them. I wanted to remove the boots so I could paint under them a little ways and not have to mask off around the edges of the boot. I CAN'T GET THEM OFF! I pulled as hard as I can with my hands and they won't budge. I tried prying with a screwdriver just a little bit and that didn't work either. It is liked they are glued on........I have a new Moog idler arm and I can pull that boot right off.

I read of people getting new tie rod ends but using their original boots. They must get the new boots off somehow.

Will these tie rod boots come off?.....and is there a trick to doing it?

Thanks.............Dave
116  Camaro Research Group Discussion / Restoration / Re: Tie rod ends won't thread into sleeves on: December 20, 2012, 08:48:12 PM
I have tried every possible combination of putting these together with the same results. I am going to give Hotchkiss a call and see what they have to say.
117  Camaro Research Group Discussion / Restoration / Re: Tie rod ends won't thread into sleeves on: December 19, 2012, 10:56:16 PM
I understand how the RH, LH thread mix up can happen. I do have them in the right end though. Some will go in just a little, some half way,  and some close to all the way.
118  Camaro Research Group Discussion / Restoration / Tie rod ends won't thread into sleeves on: December 19, 2012, 08:48:17 PM
I have new Moog tie rod ends and Hotchkiss tie rod sleeves. I was putting them together today and am having problems threading the tie rod ends into the sleeves. When turning them in by hand, they will go in freely part of the way....then I start feeling resistance......and then they stop turning altogether. Far short of going in all the way. I don't want to apply any more pressure for fear of stripping the threads.

The threading on the tie rod ends seems to be OK. I can take the locks nuts provided with the Hotchkiss tie rod sleeves and spin them freely on to the tie rod ends, all the way to the end. There must be a problem with the threading in the tie rod sleeves.

The Hotchkiss tie rod sleeves are 5 1/4 in long and it looks like the threads on each end go in about the same distance. There's maybe an 1/8 inch not threaded in the middle where the RH and LH threads meet. That being the case, you should be able to screw about 2 1/2 inches of the tie rod end into the sleeve...........In my worst case scenario, by hand cranking it, I can't get the tie rod end more than 3/4 inch into the sleeve. Some will go in further but not all the way.

Just wondering if any one else has had this problem and what they did about it? Maybe they will go in all the way by using a wrench but every time I crank hard on something that doesn't want to go, I end up with a lot of trouble.

Thanks.......Dave


119  Camaro Research Group Discussion / Restoration / Re: Upper control arm shaft - How important is this surface ? on: December 15, 2012, 11:15:20 AM
Thanks guys for the info..............I have question about emery cloth. I often read people recommending emery cloth for polishing metal but no one ever mentions a grit size to use. It comes in many different grits. Does the abrasiveness of a certain grit of emery cloth equal that of the same size grit in sandpaper. If you are recommending 1000 grit sandpaper or emery cloth to polish the ends of these shafts, would I look for the same grit of emery cloth or something different?

                Thanks,
                Dave
120  Camaro Research Group Discussion / Restoration / Upper control arm shaft - How important is this surface ? on: December 14, 2012, 10:42:40 PM
On each end of the upper control arm shaft, where the bushing sits, how important is the surface condition on this area? Mine have some rust pitting. (See the attached photo with the arrow) .

I am trying to figure out if the shafts I have will still work or should they be replaced.

This is my first time redoing a front suspension. Tell me if I understand this correctly....... With the bushing in place on the control arm shaft and the bolt with the large washer put through the bushing and screwed in to the control arm shaft, the serrated edge of the bushing's inner sleeve digs into the control arm shaft and locks them together. The inner sleeve of the bushing never rotates around the end of the control arm shaft when the car is being driven.....Is this right?

If the above is true, it would seem that the surface of the control arm ends would not need to be super smooth..... Right or wrong?

Any thoughts would be appreciated.

Thanks.....Dave
