When I removed the rear side panels on my car I noticed that originally there had been some type of foam on the curved portion,,towards the rear. Most of it was dust on the floor, very little was still on the plastic panel. Can I replace this maybe with some spray insulation foam? Do I need to? How much was in there?

I would use regular low density foam. They are about 2" blocks about 10" long. They are mounted where the interior panel comes close to the wheel housing.
