Mike S.,

Any status/opinions on the firewall pad you ordered?

Thanks,
Paul

Hi Paul,
Yes....it is interesting. Let me put the pictures together and I'll post them.

Mike
I started a separate thread (Tamraz firewall pad).
872  Camaro Research Group Discussion / Restoration / Tamraz firewall pad on: June 04, 2012, 09:03:27 PM
 I bought the firewall pad from Tamraz because the texture looked rough like the factory pad and not smooth like so many of the rubber coated replacement pads on the market. When I received it I found the material was not rubber coated like the factory but it did have the rough textured look. The thickness of the backing was approximate to the original. I felt the search for the exact reproduction still continues.
 The other day I was in Home Depot and had seen a can of rubber spray. So I figured being the Tamraz pad had the texture but lacked the rubber coat, what the heck it was worth a try.
After tacking the pad with a lint roller to remove the loose fibers and giving it 4 wet layers with a 30 minute flash between each layer to prevent solvent popping, I was surprised how it looked and felt  just like the original pad though a slight heavier weight. But, being most will be concealed under the dash hardware the weight didn't matter to me. It had the texture and rubber feel that I was looking for. I will be using this pad as my replacement because it looks that close to an original until I can find the true exact reproduction pad.

Now mine is a BB if that matters compared to your application. That spring prevents the weight from chattering against the shaft.
The small coil spring (not copper) prevents the shaft from chattering in the housing. If you put your hand on the weight when you first start the engine you will feel the weight oscillates quite a bit with the exhaust pressure pulses so you can see the potential for mechanical chatter.

Hi Steve,

  See the image from my restored L35 for the location. I checked my survivor L35 and it has the same spring too.

 It is supposed to keep pressure on the shaft so it doesn't chatter from the exhaust pulses. It doesn't hook into the shaft, it just presses against it.
I see yours doesn't have the small barrel spring on the shaft the weight pushes up against when fully open.

....... If the car truely didn't have a radio, or had a rear antenna (an hence an AM radio) from the factory, there will not be a holde drilled in the A piller forward of the passenger door where the antenna cable went from the interior of the car to the space behind the front fender.  If theres a hole there, then the car had a radio when it left the factory.

Mark,

 Are you absolutely sure about that being no hole in the front pillar if there was a rear mounted antenna ordered?
I do recall seeing a rear antenna 67 (option on trim tag too) with the front hole (looked like it was punched) with a plug in it.
The AIM refers to it as 'existing hole' and I figured it was like so many holes punched and plugged based on options.

I agree, to me the original cars are very cool to look at, and to me it doesn't matter if its a six cylinder or V8, Mustang or Camaro. Seeing the original patina and preservation of a classic, is  a little special. I still enjoy restored cars, but the survivors and drivers are what I appreciate. There will always be trailer queens out there, and they are part of the hobby as well.....

I agree entirely. I'm a 'stock' guy. When at a car show and walking towards a car that looks stock on the outside and if I see an aftermarket air cleaner when getting closer, I'll continue to walk past it. But if it passes the air cleaner housing test, then I'll stop and give it a long study no matter what brand or model as long as it is stock.

Parts for my Harley are made in China. It's sad to know even HD joined the corporate whores to use cheap foreign labor.
I heard GM may move the manufacture of the Volt to China.

Hi Gary,

 I had my 4 piston calipers sleeved with SS inserts in 1987 and still holding well though I did install new rubber seals recently just for the sake of it.
I had a local shop by me called Apple Hydraulics ( http://www.applehydraulics.com/brakes.htm )  install a brass sleeve for $95. They do brass and SS but I opted for brass to save some $$$$.
They do complete rebuilds or just install a sleeve and you rebuild it. I went for option 2 and got the rebuilding kit locally at LI Corvettes ($28) and saved quite a bit ( over $100 total ) doing the rebuild myself.

881  Camaro Research Group Discussion / Originality / Re: 67 under body dichromate primer? on: May 29, 2012, 02:57:05 PM
 I found the answer to my own question from a buddy who works in a paint shop. He used a rag with some compound and was able to get a deep gloss from the yellow that was like the topside body color gloss. Cool idea! The red primer area he rubbed had a slight shine but nowhere like the gloss as the yellow. He did this to show me the difference between the two to rule out the yellow being a form of primer. He said it was likely darker because of the red oxide primer under it vs. the gray primer used on the topside and the fact that is was mainly thick overspray even though the whole under carriage is yellow over red oxide primer right up into the tunnel and stops at the floor meets cowl line. I still donít know how a reciprocating sprayer would reach so far under unless the fan size was very large, and seeing other examples of the same coverage on other posts, I'll go with what I found.
 So, if the results donít follow the theory, keep the results and change the theory.  Wink
  So this is how Iíll restore the underside

  I have rebuilt both and it's impossible to see the SS inserts on either the M/C or calipers when installed.

883  Camaro Research Group Discussion / Restoration / Re: 67 repo door skin experience? on: May 27, 2012, 06:52:09 PM
 Thanks Daniel. I may go with the whole door shell from dii being their are no P/N's stamped into it and I checked out the ribbing and it's the same as the original door.
Either way if I get the skin or whole door, I'll post my results about it for future reference.

884  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.
