Just purchased a 1970 fj40 with 3 on the tree, the drive train was removed bad engine. I have all the old parts.I also purchased a restored 1973 frame with a 4 speed and front disk brakes. I Am thinking the quickest way back on the road would be to put the 1970 body on to 1973 frame. I most likely have a 4 speed transfer case so I am wondering how much floor cutting I will need to to do. I plan on putting the 70 body back on the 70 frame down the road. Thanks
