Are you talking about the inside of the fender area's where the tires are? If so I believe they were sprayed with a sound proofing material that is black or became black over time.

This is great info. I knew about the padding but didn't know about having to do the entire interior. How do you get it remain in place on the roof and doors?

So why was thick stuff put into cars? I've got a 76 Duster that I blasted all that way. I've used Damplifier Pro and did the entire interior of the car.

I went to Autorama today and took prolly 25 pics of this car. It's insane! Nice to see a couple of Mopar's in the Great 8 to win the Ridler.
I'm uploading pics now....

If you find 1995 ACR seats from a Neon they have high bolsters and side bolsters than the rest. Barring that the SRT-4 Neon seats are pretty much race seats.
But any of the R/T or ACR seats are better than the base model seats.
