Well I am trying to get the gas tank into my Charger so I have been acquiring the parts to complete that install. I went and ordered a replacement filler neck, new tank, etc. Well I went to get a replacement pad for the tank to trunk floor, what a headache. There are 3 major types of pads, foam rubber, 30lb roofing felt and one supplier of originals. So from what I can tell, the foam ones retain water. The 30lb roofing felt has changed since the 80's, I measure some today and it was only .017" thick where the orignal pad on my car measured .063. The original replacement pad was $159.99 from Jim's Auto Part. Well after further searching, I found that DMT carries one that is almost the same thickness as the original from their ad. So I ordered one from them on the bay, hopefully everything is not like this when ordering parts...I will post on the quality when I get it. Tim
