Rebuilding the dash on My 73 Cutlass S and need a good replacement for the foam insulation that covers air doors, and vents. Mine are shot/crumbly. Also looking for a good replacement for the insulation that covers the mountings for the dash. It's not specifically the firewall but it is attached to it. It was some kind of plastic (like a garbage bag) covered fiber/batt insulation.

Thanks.

 

That self-stick foam matting (like dynaliner or fatmat) works good for dash insulation.

Definitely looks like the stuff I should use. Now that's the easy part. Now I have to find a dealer closer to the great white north. Thanks for the info.
