I had to replace one spindle the spindle on this truck because it was damaged. I was sold a an NOS 3797525. This spindle fits 1960-1962. GM books show 2 part numbers for these years but they are interchangable (Holander interchange).
Now I have one original spindle and the one replacement again due to damage. If that spindle hadn't been damaged. I would not have needed to replace it.

1960-1962 spindles are the same.
1962-up hubs use tapered roller bearings.

The ball bearings use a removible race located on the spindle. Slide that race off and the tapered wheel bearing slides right back on. Even the newer seal diameter is right.

Restated: Today, I took a ball bearing hub off my stock original 1960 spindle, slid the inner ball race off the spindle and slid on a 62-up C10 roller bearing hub.

One thing I forgot to mention, You will need also need the spindle nut washers and dust caps from the newer truck. they're smaller in diameter
