So to start i have a 74 FJ40 with a F and H42 4 speed tranny. I would like to stick a toyota diesel into it. I been reading and it seems that a H series diesel will work the best for me, aparently they share the same engine mounts and bellhousing and tranny input shafts. Correct me if I wrong, toyota diesels are new to me. I would like to keep my tranny and t-case. Also i would like to run saginaw steering so would a sag. pump bolt onto these diesels? Any info on these diesels would be great!
