Would an '83 pickup be the correct flywheel. Definite large center hole for crank register. Definite cast crank motor but...... might have been a hydraulic cam motor. (Had an odd shaped valve cover in bed). Not sure if that has an effect on engine balancing.
Parts list will vary depending on which system you choose to use. But generally two (2) each of spindles, calipers, caliper brackets, dust shields, rotors and brake hoses. Also one (1) each of master cylinder, proportioning valve and several metal brake lines.. This list above applies more...
I waited to answer thinking there are bound to be some closer to you than mine. Price would be about $80 each shipped. Mine can be seen on Offerup.com/tucson. Appreciate they won't be your first choice, but worth keeping in mind if nothing else comes along I think Steve.
