Model A Ford front caster
I have been told that the frame on Model A's establishes the front 5 degree caster angle and the front radius rod when mounted on the bottom of the bell housing reinforces the setting. Judging by the number of front end collisions a Model A might have in its life and the fact that the front axle is symmetrical and does not establish the caster angle unless further bending of the king pin bores section of axle between it and the spring perch holes is bent back. How would one suggest checking a frame for the 5 degree bend back?
