Acclaim wheels on an A-body?

I think there was a thread about these about a year ago. Not exactly a 4" bolt pattern from what I remember...wasent it metric? And from tests and studies, NOT SAFE??? Also, those came from FWD vehicles. I dont think the offset and backspace will be usable on our RWD cars.....maybe someone else can chime in with the specifics. I can only remember bits and pieces........
