1969 cowl hood insulation and sound blanket replacement

[Red Camaro Guy]

Any idea what the GM part number would be for the cowl induction insulation and sound deadening blanket would be and the best place to find a replacement?

Currently the Pad thickness-stiffness is a concern and installation challenge. Unfortunately the current versions are a big thick and stiff making the use of the retainers a known difficulty.

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

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.
