Will these rims fit my '69?

I just got back from the salvage yard after pulling my Grand Cherokee steering box, and in the yard was a late 80's/early 90's Camaro with a set of the factory cast 15" five spoke wheels like the ones from the Z-28's of that era. I can get them really cheap, but without pulling them and trying them on the Chevelle I don't know if they would fit. Can anyone out there tell me if the would work on my '69 w/ discs up front and drums in the rear? Thanks!
