826  Camaro Research Group Discussion / Originality / 67 under body dichromate primer? on: May 27, 2012, 02:46:30 PM
I know this topic has been discussed may times before. While scuff sanding the underside of my 67 NOR 5B convertible I see the whole underside is covered in what I thought was butternut yellow paint. But what is confusing is this appears in the upper parts of the transmission tunnel too. I have researched and read the articles about the underside colors and the finishing process on CRG, so the underside is said to be anywhere from red to black to gray but I find it hard to believe the underside would be completely painted in the body color considering the painting was automated (minus blackouts). What I have is not just overspray because it is too uniform and applied on purpose and on areas outside the robotics reach.

 In the attached picture (Pic 1) the underside layers are as follows from bottom to top:
raw metal --> red primer --> yellow coating (paint or primer?) --> Rustoleum I applied in the 80's.

Looking at the topside body color picture (Pic 2) the layers are from bottom to top:
Raw metal --> factory gray primer --> factory butternut yellow paint --> (repaint) gray primer applied in the 80's --> paint applied in the 80's

The picture with the paint sample (Pic 3) of the 80's butternut paint job was scuff sanded the same grit as the underside to remove the gloss. As you can see it is noticeably lighter than the yellowish hue of the underside as well on the chassis rails that are completely opposite where the robotic sprayers overspray would hit.
If this isn't paint then this leads me to believe that a yellowish primer was also used, possibly a form of dichromate?

The gauges in my '67 console have a white sticker with the broadcast code and date.

828  Camaro Research Group Discussion / Restoration / 67 repo door skin experience? on: May 26, 2012, 04:00:46 PM
  What I thought would be a routine door skin replacement on my left door turned out to be a surprise once I removed the original skin and went to install the NOS one.
A spare L&R 67 NOS set I bought in the mid-80's and stored since then turned out to be a mis-matched set. The right skin is for a '67 but the left is for a '68 Camaro so that is useless to me.  Shocked
Looking for a NOS panel on ebay averages $500. That's an expensive price to pay for a GM sticker on the inside.
  Has anyone installed either a repo skin or a complete repo door assembly? If so I would love to hear your experiences on fit and quality.
I am looking at Dynacorn and they boast of superior repo parts but then most repo places do.

Thank you,
Mike

Whitepost has some interesting cars there and looks like a top notch shop.
I received a separate email suggesting a place called Apple Hydraulics. I checked out their web site and leared they are only 10 miles from my house.
I stopped by there yesterday to drop off the master cylinder and got to speak to the folks there.
Anyhow, they will clean, glassbead and sleeve the cylinder at the cost of $95.
I'll be installing the rebuilding kit myself (including the rear drum line check valve)

Thanks for the reply!

 If you have the resistor wire intact and a stock type coil (2 wires), then it should work fine poviding the distributor is properly indexed.

 It's time to get the master cylinder sleeved after 45 years of use.
Can anyone recommend a place that they have had good service with?

Thank you,
Mike
832  Camaro Research Group Discussion / Restoration / Re: Restoring engine back to points: what's needed? on: May 24, 2012, 05:49:19 PM
In addition to Big Iron's question, did you save the original resistor wire to be used with the stock distributor?

833  Camaro Research Group Discussion / Restoration / Re: Fisher Body Paint Shop on: May 23, 2012, 07:52:15 PM
here is two 69 , 1 lemans blue and other rally green




I know this is an old thread but in the process of re-restoring my 67 5B NOR ragtop and wanting to return the underbody to the correct finish method, I have been studying this topic in detail for a long time and have also read the 'Process Overview' article many times.  When I restored the car back in the mid 80's I scuff sanded and sprayed the under body semi gloss black for the clean look. I remember seeing yellow but I never kept record of how much.
 Now I want to undo that. No matter where in the undercarriage I sand I uncover the following layers (going from top layer to bare metal).....top layer-->  black (my paint from the 80's) --> butternut yellow (original body color and paint) --> red oxide primer layer--> what looks like a dark gray or black very thin layer (phosphate?) --> bare metal. There is no gray to be found underneath so far as reports suggest should be there and overspray over that.
  What stumps me is the whole bottom has a layer of butternut yellow including deep inside the tunnel at the top...as if the whole bottom was sprayed. I figured the robotic sprayers would hit the bottom edges mainly and not so much up and into the tunnel top.
 These pictures, especially the green example,  prove to me that it is possible to have an almost underbody color the same as the top coat. It may sound anal but I am so relieved to see this example and know it can happen. Smiley

Bob- no....I'm a '67 guy  Wink

Ed - Thanks for the link. Yea....it sure does look like a Mustang. But the Ebay link above looks more like the console shifter identification plate being it's a 2 piece design.

Interesting to see such a thing existed!

835  Camaro Research Group Discussion / General Discussion / Re: Is this a Non-Console Automatic Floor shifter? on: May 21, 2012, 01:22:01 PM
 So the ebay ad shows the shifter but the console plate shown was not used for cars with no console?
What was the means to show what gear the tranny was in?

836  Camaro Research Group Discussion / Originality / Re: What is the assembly line correct 68 Rochester 4-bbl carburetor choke pull-off? on: May 21, 2012, 12:16:10 PM
OK Both my carbs are Carter built Q-Jets so that might be where the difference comes in.

Did Carter built QJ's also have "RP" stamped pulloffs, I wonder?
Most of the parts on a Carter QJ don't have an RP stamped into them so I assumed that the pulloff didn't have it either.

837  Camaro Research Group Discussion / Restoration / Re: AMD Suframes - Quality, fitment, and finish ??? on: May 19, 2012, 11:03:56 AM
I'll find the exact article. It was either Hemmings Muscle Machines or Chevy High Performance I read earlier this year. It clearly mentioned inward chassis sag due to the design which can lead to adding more shims and it specifically referred to the repo replacement. I never thought that as a possibility until I read that and I never heard of AMD before that article so I went to the web site they posted to read more on the chassis. I was considering it for my hardtop when I restore that but decided to keep the original one out of nostalgic reasons.

838  Camaro Research Group Discussion / Restoration / Re: AMD Suframes - Quality, fitment, and finish ??? on: May 19, 2012, 07:37:00 AM
 AMD claims the chassis sags over time which accounts for the need to add more and more shims to the caster/camber. If that is true then wouldn't it sound logical that even though a used 40 years +GM chassis is available that you would still face the same sagging issues?
  Just a thought.

839  Camaro Research Group Discussion / General Discussion / Re: 68 Camaro TH400 oil pan on: May 18, 2012, 09:41:05 PM
 Unless other 68 owners here can verify this, I don't see that ad being accurate in stating for 67 Camaro.  My 67 4B L35 has the original TH400 and it does not have that pan.
Many times I have seen eBay sales to be misleading or wrong.

Give Pace Car Jeff a call. He has LOTS of dip sticks and is knowledgeable about them too.
I thought the dimples came later too.
