I put P-3500 HD front hubs/spindles on my GMC ‘55.2 front axle. Had new king pin bushings made,($12. ea) ,no other changes. Used ‘60’s tie rod. Spindles need to allow tie rod to reside behind axle. Note: there are at least two types of grease fittings going into king pins, make sure yours are properly lined up(simple). Measure thread pitch carefully, drag link, tie rod, etc., I have found 16 tpi and18 tpi on same truck, hard to tell apart unless measure.
Installed right width D-80 disc brake rear axle, made shims to fit different diameters. Found another set of front spindles/D-80 nearby.
One can use 22.5” wheels with 5/10 bolt pattern(rare), 19.5” wheels with 5/10 bolt pattern (common) or make wheels from scratch or redrill 22.5” wheels with 10 on 8.750” pattern by redrill ink and spacer.

Ed,
Thank you
To be clear, are there different 3500HD axle configurations or were they all steering behind the axle? I mentioned in another post, I *may* have access to a 2000 3500HD front axle assembly, but it appears the steering linkage is in front of the axle. The guy cobbled things together....I can't hardly imagine he reversed the rotors/hubs or even flipped the axle but who knows? It is currently in a 1959 Chevy LCF, the rear in that truck is an 8 lug Dana 70. I want matching wheel lug patterns front and rear.
Will most any Dana 80 rear end out of a '99 to 2002 Chevy 3500 HD work as well with respect to track width under my '50 COE flat bed? Whether it a truck or a motor home?
Thanks again Ed, really appreciate your thoughts and insight.
Perhaps you would allow a phone call to set me straight, but sharing the info here will be good for future users seeking the information.
