3/4-t vs. 1-ton spindles - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I picked up a front cross member from what I was told was an early 70's 1-ton with disc brakes. I'd like to use the spindles for a disc brake conversion I'm doing on a 3/4-ton '65. Were 1-ton and 3/4-ton spindles the same in that era? Is there an easy way to identify what I really have?

Bump.....anyone know?

I believe if you have single rear wheel 1 ton spindles its the same but if you have dually spindles they're different.

Thanks for the par numbers. With a little luck they'll match the numbes on the spindles. I'll check tomorrow.

The spindles on the front end I have carry the numbers 3989485LH and 3989486RH. Does your parts book show anything for them?

Thanks,

Looks like the same service part numbers for C20-30 and G30 w/DB. No mention of DRW either way.
