I used a bit of that aluminium-backed carpeting insulation in my cab on the firewall (1" thick) and floorboards, it killed a lot of the noise. After doing so I realized I'd have to rip sections of it out to do an Engman Long Stiffening Kit. So I'll order more, and I just recently purchased a large 48" x 80" roll of Neoprene insulation for $20 shipped. This gives me plenty of material for the whole car (trunks, hoods, doors, cab, etc). Combined with asphalt-rubber based insulation in the engine bay, I think I can cut the in-cab and car/road noise down considerably. Hell, just adding insulation to the f/g top removed a lot of it. Unfortunately the glue I used was crap and a few days with the heat of the sun beating down on the top it all fell off. I'll re-try with the Neoprene which should be lighter as well. Neoprene is waterproof too, I think.
