Hmm. On my 1500 they are not riveted on, just held on by the lug nuts. But the center bore is a proper fit.
I'd say that the center bore needs to be the right size.
Can't imagine why GMC would use a different drum than Chevy.

What is the diameter of your hub?

I'm looking at Rockauto for a 1965 1000 series, the drums I've looked at list a 90.5mm (3.57") center bore.



Let us know what you find.
