So needless to say, my 82 C1500 is not the quietest cab I've ever been in. There is a nasty whistle coming from the windows... Believe to be the weather seal... But mainly it's the noise from the truck and the noise from the road. Now maybe I'm just whining to much, but come on I can't even hear the stock radio when it's turned all the way up! :P So the best idea I had was to Dynomat the entire cab. Well unfortunately that sh!# isn't cheap! So the next best idea I could come up with was to go into Home Depot or a carpet store and try to find some kind of High Density Poly Urythene foam padding, or thin dense carpet padding. And run it under my rubber floor cover, behind the door panels, cab side of the firewall, on the ceiling, and behind the bench. Does anyone have any thoughts, ideas, or comments on this. Since I love the body of this era truck and love the versatility of motor and transmission options, I am thinking I will invest my money into making this truck my "NEW" truck. Since I am not to fond of the 20 million look-a-like trucks out there.
