Axle castle nut 65 c10

[cab_01]

I have a 65 c10 that I need to get the part number for the front castle nuts that hold the bearing, washer and drum onto the spindle. anyone have any idea what those numbers are?

On a C-10 2WD should be 3/4"-16 thread 1 1/8" hex
Dorman part number 615-002 or 615-040

IF you have 7/8"-14 thread and 1 7/16" hex:
Dorman # 615-001 or 615-026

These are sold at most parts stores or they can cross these numbers

Hope that helps
