Does it go on all four sides ? are just three??

It only goes on three sides.

The foam gasket, seal is about 1/8" thick and 9/32" wide. Currently looking to source the most accurate foam for the gasket. Anybody have any ideas for a source on material please post it. As an fyi the material is open cell and can compress more than 50% of its thickness.

Dan

I have a small piece of the seal in question. I will try and take a picture of it as I too am interested in where to source the seal from.

My response is consistent with what Jim (169indy) has said. All be it the under hood insulation has a few minor issues the overwhelming one is the thickness and density of the material. With the combination of thickness and density it will not compress at all. That being said you cannot make the factory style clips seat and lock without them splitting them. If you do manage to get one to seat it will over time split as well.
What I did and it was cumbersome and time consuming at best was to spot face (dish) each location where a clip was to be installed. I did it from the side facing the engine compartment when installed There is no good method that I could figure out so I combed it (remove material) with a razor blade. You need to remove enough material (it will be thin when done) under the clip disk so that it will lie down flat and won't be seen after the clip is installed. Conversely you could do it from the back side as well. I did get it to install using the factory style clips but set aside an afternoon to work on it.
I'm sure there might be better ideas on how to fix it but this is what worked for me.

I will post it this evening.

Anyone who is interested in the installation details let me know. It is not just put in place and secure it with the clips.

I was at a local car show a week ago and spotted a 1969 Camaro. Taking a closer look, it was 10E (Oct. 68) LA built Camaro. Looked between the rear quarter panel and rear tire and found remnants of black paint on the gas tank. There was also black paint on the rear springs. Just another observation of LA built Camaro's.

Thank you HansL for posting the link. Again William points out several things that were unique to an LA build. I found this old post "van nuys firewall markings"; http://www.camaros.org/forum/index.php?topic=14307.0
In the body of the post, firstgenaddict has a post showing an early 1 owner unrestored 69 Z28. In that picture, it clearly shows how the stripe masking was done (soft edge at cowl, firewall intersection). That too has been my observation looking at 69Z28's built at LA.
HansL I will be looking through some of my old pictures and try to find other details unique to LA builds. I've sure enjoyed the responses to the original post and look forward to future ones.

Thank you for your post Kurt as bare rear leaf springs is what I have generally observed too. I'm now turning a corner which does not suggest black paint was used only on LA Built Camaro's but also on many other GM Product lines. General Spring was the main manufacture, supplier to GM starting in the mid-sixties. I've traversed through a few websites relating to first gen. Camaro's and Firebird's and also second gen Camaro's. There have been posts on each of the sites discussing the black paint on rear leaf springs and how to duplicate it when restoring them.
So here's my theory. Black paint was used to prevent rust during transportation and storage at GM Plants and it's longevity was probably limited. I'm guessing that they weren't even cleaned (prepped) prior to paint. With that in mind, I'm guessing the paint had a very short life span. Unfortunately without having a process spec. from either General Spring or GM the black paint found on some springs may be relegated to myth.
My car is an LA built 1969 Z/28 with an assembly date of 03 B and spent most of its life in Southern CA. When I acquired the car in the early eighties there was virtually no rust anywhere on the car. As mentioned in my initial post, my springs are coated in a black paint (utility type) on both sides from end to end. As best I can tell there's no black between spring leafs which suggests they were painted assembled.
The journey continues and I look forward to hearing more input from members.   

Where was the selling dealership?

I've enclosed a picture of a LA built (Feb. 69) Z/28. If you zoom in you can see the soft tape line of the Dover White stripe at the cowl.

On 69 Z/28's built at LA, the stripe color that (in my case is dover white) continues to the edge of the cowl. I've spent mant years observing how this was done. In general, LA cars have a soft edge tape line with no overspray onto the firewall. What I mean by a soft edge tape line is that the stripe termination is not perfect. I'm going to look through my picture collection and post a few examples. Is there anyone out there that has noticed this detail as well?

Dan

Thank you William, I've learned some new details I was not aware of. I plan to add a few more today and look forward to feedback.

Dan

I think that's a great idea! We would probably need to start a new post (blog) and this might be the first entry. Maybe Kurt could help us set something up.

Dan

Thank you to both of you for your input. It's been a journey learning about the differences of how LA built Camaros as opposed to Norwood. The black paint on the rear leaf springs has baffled me for years. With far fewer Camaros built at LA, I'm sure I will run into more items that are LA specific.

Thank you,

Dan
