Wayne, we make tanks to fit in the factory location but only for our own projects since this leaves the underbed spare tire area open. If you want to use the rear of the frame then a Blazer tank is one commonly used. If your tank is beyond saving a sheet metal shop can easily make you one since you already have the frame mount brackets. Here are a couple pics of a tank we made for a 48. The first photos show the factory tank in the truck (bottom is gone) and then the nearly completed replacement which doesn't have the filler tube or sending unit hole at the time the picture was taken. Scroll down to first few pics on page one. http://s32.photobucket.com/albums/d41/coilover/
