Bill..  Just read it and responded.   Thanks.!

We'd all love to see those color pix of the new '69 Z28.... taken in the day!  Smiley

William,

My tailpipes are correct and have the chrome tips;  I can't recall if these were on the car when I purchased it, of if I bought all that new in the '70's.  I do know I bought some things new; I even bought an almost complete chambered system to put up (and use when I restored the car)...  but of course the chambered is not correct for my car as I now know.

I have everything correct and in good shape except the exhaust pipes and resonators.  Is Gardners the only source for correctly configured exhaust pipes?   

Back when..   good muffler shops had cards which told how/where to bend the pipes to duplicate the factory parts...   Don't they still have those cards and do that?

My '69 Z28 has the original pipes over the differential and behind the diff muffler and tail pipes, but I've ran headers since I bought the car in the '70's, and thus had a 'muffler shop' connection from the headers to the differential pipes. Question: Is there a source for *original type* exhaust pipes from the factory exhaust manifolds to the rear section? I think this would consist of the exhaust or header pipes and the resonator section (for my late 09C '69 Z28).   I have the original 'day 2' takeoff exhaust manifolds which I plan to use.
If there is no source, is my only option to have a muffler shop bend up a replacement?

I agree T-model66..  appears to be an extremely well-preserved original car, which is also very *rare*.. YES,,  Camaros with bench seats are rare... 
a bench seat in any of the pony cars are rare; I didn't even know a bench seat was an option in those cars until long after they were new.. and I've only seen a handful in my lifetime since. 
Note:  I assisted a good friend with restoration of a '70 AAR Cuda, with bench seat and column shift Auto ..  How rare do you reckon that is?  Smiley
2016  Camaro Research Group Discussion / Restoration / Re: Are the any differances in sub frames? on: November 13, 2012, 01:29:55 PM
I might be preaching to the choir but I have always used a piece of 1/4" cable to keep these things from killing you. It's old school but I was taught by old school mechanics. Take a piece of cable and circle the spring a couple of times and put a couple of clamps on it. This way if the compressor slips it can't go anywhere. The cable will keep it from expanding any further than it was when you captured it. It works real good and might save a disaster. 
I also learned from 'old school' mechanics, and similarly I use a heavy chain around a couple of spring coils and around the frame as a 'safety precaution' when removing or installing coil springs...

If the purpose of this was 'heat insulation' from the muffler, what is the possibility that when they changed the exhaust configuration, and added the resonators forward of the muffler, that they also deleted this material?   There would be more heat dissipated forward of that point, and less heat at the muffler with that change....
Gary  / 69Z28-RS
Gary, all deluxe interior cars were provided the sound deadener( I've seen it on a 10C of 69 and is also on my 9c of 69 car).
Interesting point Ed makes that its purpose was to dissipate heat. My feeling is that the trunk floor deadener purpose was to attenuate any noise / resonance due to the rear axle and suspension in the open trunk area. The material they use I wouldn't classify as heat resistant.
Ed where is this referenced "It was designed as a heat barrier to keep the heat from the muffler from melting/deforming the trunk mat".

Steve,  I appreciate your comments, and it is interesting that some later cars had it when mine apparently did not.  My car still has the original trunk paint and trunk mat, but no evidence of anything ever having been glued in that location on the trunk floor. (although there is some deteriorating material falling into the trunk area from the hat rack area above which seems like sound deadening material?)..   I agree with you that a tar-based material would be used for noise purposes, ie. 'panel vibration damping', rather than for heat insulation.  I doubt it would provide any significant heat insulation..

My 69 has no evidence of ever having had anything like that...  I've owned it since 1975-76....

I suspect someone added the tar paper and undercoating in trying to quieten the car; 
My 09C (late) production Z28/RS (with custom cloth interior) does not have any tar paper or undercoating on the floor of the trunk.

Tmodel66:    Aren't we all sorta weird?  To be spending so much time, effort, and $$ on 40+ yr old cars??   Smiley
2022  Camaro Research Group Discussion / General Discussion / Re: Official CRG Cap and T-shirt? on: November 12, 2012, 01:10:59 PM
Agree on the white:   I wear T shirts mostly in the summer months, when it's HOT, and when I'm at a car show (OUTSIDE- repeat HOT) I'm wearing car related T shirts...   WHITE reflects most of the sun's heat....  Smiley

PS>  To reiterate what was relayed from Steve's wife:   the number of colors (and screen/masks) are what drives the cost more so than anything else.   With front and back logos, you have separate screens for each color (for each of the front and back)...  so with red/white/black on front, and red/white on the back, you have five screens involved.   If you stick with one color per side, you have only two screens...

2023  Camaro Research Group Discussion / Originality / Re: Source for 'EY' Coil Springs for '69 Z28/RS?? on: November 12, 2012, 12:53:56 PM
Rich,

Maybe it's the perspective, or just my eyes, but to me, the car in that photo sits a bit higher in front than the original Z28's did...  I think it should be just a bit lower in front than in rear and that one appears to be a tad higher in front than in the rear.   
I ordered some 6320 springs and received them, but there were visible differences in that spring and my original:    original:  8 loops; 0.605 wire and the 6320 had 10 loops with 0.64" wire size.   I returned the 6320 springs without using them.

There was a burgandy Z28 in my town in the 70's with RED interior; it had white stripes, but the red stripes might have gone OK with it..   (I thought there was a color mismatch between the burgandy paint and red interior....ie. didn't seem to me to 'go togethre', but it was original).

PS.   Back in that time frame, a buyer *could* special order a 'non-recommended color combo', but it had to be a 'SOLD car'.. before build.

2025  Camaro Research Group Discussion / Originality / Re: Source for 'EY' Coil Springs for '69 Z28/RS?? on: November 08, 2012, 11:58:10 AM
Following up on my previous email:   When I disassembled my original Z28 front suspension for rebuilding, I found one of the original springs (EY tags) with a broken coil...  I want to replace my front springs with the closest I can find to the original spring, both in height/looks and performance.

Based on information from Steve S., I sent my good 'EY' spring to Coil Spring Specialties in Kansas, and have been discussing with them my options.  They have spring steel of slightly smaller diameter (0.59")  than the original (0.605") and slightly larger (0.61").    I want the spring to end up with the same number of coils as the original (8 total coils), and I desire the installed height in the car to be the same as original Z28s.   I can request the 'free length' as manufactured to be whatever I desire, in order to get the installed height (in the car) to be what I need, unfortunately, I'm unsure what that is since my front end is totally disassembled currently. 

My question is:    Does anyone have a source for the design-spec compressed spring length for a '69 Z28?? 
If not, does anyone have a Z28 that is sitting at the correct height (for a Z28) that they can measure the compressed spring length (ie. from upper pocket to lower pocket with all weight on the wheels and it's springs)?
