Last week I tried putting mine (I have an '85 IROC) on the Firebird just to see if they would fit. I had heard that the fronts would go on the rear and rears on the front. That did not work, rubbed at the rear. I think it would only work with two sets of rears. Even then the fronts rubbed a little with rear set mounted there. Looked great though. I would post some pics if it wasn't such a pita.
