Difference in Dana 30 disc and drum hubs?

I'm picking up a set of lightly used 6 bolt hubs from a friend, and ran into a question on them. I'd been looking for a pair for awhile, and checked Morris and Qtec, and noticed Morris has two types on their site; one for drums and one for discs. I mentioned this to him, and he said he wasn't sure if the axle they came off of was disc or drum because it was bought for parts and stripped.
He told me, "I pulled them off of a late 70's narrow track 30 but never ended up needing them." He also said he did the same swap and with the two hubs up next to each other, he couldn't tell a difference.
I'm waiting on pics of the front and back and I'll post them here if that will help get an answer.
Thanks for any help.

The factory drum hubs do not have the backside machined flat for the rotors to install against.

Ok, thanks for the reply. He said he doesn't think they look machined, so he's thinking they are for the drums. He offered them to me for free, and was thinking maybe I could get them machined to work? I don't know if its worth the hassle or not.
