Hello guys, I have a 1971 FJ40 with a converted engine and transmission which is from a 1981 BJ40 (2B; 4speed). I need a new fuel tank (diesel) that would suit this setup. Do you have any suggestions? The more options the better. If available, can you kindly give me outside dimensions of each tank and the links to these tanks for me to view and purchase if any? Would appreciate it very much. Many Thanks! By the way, would really like to keep the original fuel filling hole location of the 1971.
