l was wondering if rims off a 1985 Corvette fit on a 1994 Camaro z28?

The bolt pattern will be the same as long as the number of lugs are the same. The only concern you might have is if the tires are to wide to clear the fenders when turning either all the way left or right, but you should be ok.

The number of lugs is not of importance ,it is the space in between each lug that counts ,but in this case it might fit l think they share the same pattern but check to make sure.

Neither of the above will help u much.
Not all Chevy 5-bolt wheels have the same spacing.

The number of lugs is important. I'd like to see responder number two try to mount a six lug wheel on a 5 lug hub.

To determine if the rims fit (since both r 5 lug patterns) u have to measure between lug #1 & #3. That is how spacing is determined. If ur hub & the rim have the same measurement the wheels will fit.

An easier way is to just call ur local tire shop & they will tell u for free.
