Buy a 1972 Chevy pickup, 350 engine, 4 speed. Most 350’s in trucks were 4 bolt mains. Lots of parts for Chevy trucks. The engines still had point and condenser ignition systems. Air conditioning was available. You can easily put a tilt steering column in them. They came with disc brakes. A 4 speed tranny will last almost forever. I don’t ever remember having to change a differential on one of these trucks. Gas milage was around 15 or 16 miles per gallon.

A 1972 is too new, with electronic ignition, and smog control.
Plus plastic connectors that are probably rotten, and I don't like Chevys.
The last good Chevy truck they built was in 1964.
