1936 Ford pickup king pin bush

[hueyhoolihan]

google says when queried with, "king pin diameter 1936 ford truck":

The king pin diameter for a 1936 Ford truck is 0.8125 inches. This dimension is consistent for 1932-1936 Ford passenger cars and pickups. The king pin connects the steering knuckle to the axle.

and was carried forward for a number of year thereafter, AFAIK.

but yeah, a variable reamer would be the thing to have, i'd think.
