Hey Old, I'm new to these forums, seeing your the man everyone turns to, I'll ask my question. I installed an aluminum fuel tank between my rear frame rails, threw out the original outside rail tank.(insurance companies hate them). mine was bought for the 73-87 chevy trucks, so it fit great. I am putting my filler in the bed, will graft the side mounted door in the bed. My truck will never carry anything in the bed. In fact I'm using PPG $500 a gallon paint on the truck as well as the bed. My main question is I want my exhaust to run out the stock location behind the rear wheels, which means the pipes will run close to fuel tank. So I don't have any issues with heat, I am thinking of wrapping my pipes with heat tape that is used on headers. Do you think a couple of layers of wrap will drive down the heat around the fuel tank area?? As soon as I get my new phone I want to start posting pics of all the stuff I have listed about my 75 LWB. I spent the last 3 days on forums about 2 piece drive shaft and th400 pinion angle question I had. I think I finally got it resolved. Thanks for any info.
