Hi all, I'm needing to buy floor sound and heat insulation for the 79 firebird. From what I've read "Dynamat" seems to be the best so I'm going to go with that. I've seen pictures where it appears there are just patches here and there and then I've seen some where the entire floor from front to back is covered. The entire floor is what I would prefer but I can't find the right kit for that. I'm new at this so I guess I could be missing it somehow? Any suggestions or help is greatly appreciated. Thanks!
