Any ideas on how to finish the interior firewall? I thoughtthe rubber floor mat would cover it. I did not think that through so well did I! I have a fuse panel and heater so it,s not much area. I have some sound insulation on it. Carpet is to fancy. I was thinking morerubber floor mat or if I could find a spray bed liner in a rattle can that would build to 1/8 or more thickness that would be a good alternative.
