Trying to find bearings to fit '72 C10 drop spindles

[cjenks1970]

I'm working on a '72 C20 project truck that I'm lowering the front end on. I have a pair of Early Classics drop spindles (originally purchased in 1998) and I have a pair of C10 5 lug replacement rotors (5×5 bolt pattern) but I'm having trouble finding the correct wheel bearings to fit these spindles. Even though the spindles were never used, they sat for so long that I can't make out any sort of part # on them. I've read through other posts that this isn't as uncommon as I thought. Does anyone have any info on what bearings I should use for this application? I'm only using these items now for my mock up because I already had these lying around the shop and figured I'd use them just to get an idea of a ride height before I went on to more serious fab work and more $$. Any thoughts and/or ideas would be greatly appreciated.
