Hello all. Am looking for some guidance. Trying to figure out what year model to hunt down for a donor vehicle for a project I want to do. Looking to take the rolling frame from a 5.9 Cummins ram for a diesel Or a Toyota Tundra for a gas rig. (Haven’t decided which way I want to go yet.) And transplant a body from an fj40 on to it with a hard top. Will be looking to stretch it to a four door unit. The three big things I’m looking for 1) year model bodies/tubs without the under seat mount gas tank? 2) what year model rear doors would work best? Not sure if I can use a standard front door and put new glass in it without an angled front? 3) how do I title such a vehicle so I can drive it in the road? Any advice would be greatly appreciated.
