Just an update on the parts. Decades ago, many manufacturers built with oddball parts so that you would have to buy spares from them. Thousands of Harleys are asembled with 1/2-24 bolts.
Evidently, Warn and NAPCO did the same thing. The 10 drive pins in the Warn hub are NOT .250 ,,,they are .245.
Spindle threads are in even fractional sizes like 1 1/2,,, 2.0 ,,, 2 1/2, etc.
The spindles on the NAPCO axle are about .030 bigger than 2 1/2. I machined up a socket to fit the spindle nuts. They had already been chisled several times.
A friend made up some pins for me. The original pins are hardened but, they run against aluminum so, I'm using mild steel.
Next stop is; the rear brakes.
