newbie with conversion question, trans gone in '98 4.0 2wd, so found '96 rust bucket with wire issues, earlier toyo trans dosent have front and rear shaft speed sensor, ive got the front input figured out, drill hole and use reluctor od drum, but rear has 2 reluctor arms with magnets, longer pickup, '98 trans has similar pickup to front, and 4 arms on reluctor, 2wd reluctor does not line up with 4x4 t-case adapter, do the 4x4's use a different rear shaft speed reluctor, or adapter, 2wd reluctor had a spacer slid into convex, and no way to install circlip to shaft.
