Spindle Question

[dennislbrooks]

I have a pair of disc spindles with backing plates and rotors. The spindles look like 72 chevy C10 spindles however they have a larger inner bearing. From what I can find out the 1986 GMC C15 may have had an option for 2500# front spindles (normal C10 spindles are 1500#) with the same 5 on 5" bolt pattern.

Can I use these spindles on a 67 C10 if I use 72 upper/lower balljoints and 72 tie rod ends? The rotor diameter and thickness are the same as a 72 chevy.

Anyone heard of these spindles? The inner bearing box is Timken LM45858.

thanks
