Re: My '63 C10 "I'd rather be driving" Project
I took a look at rockauto.com and found that the brake drums for a 1965 C10 1/2 ton shows a pilot bore size of 3.564". That would lead me to believe that the axle hub diameters were 3-9/16" at the drum, stepped down to 3-17/32" at the wheel.
It's very difficult to find this info listed anywhere. Any wheel-specific information I could find only goes back to 1967, and I don't see anything with a 3.532" or 89.7mm centre bore.
