Do you have the 16 inch IROC rims for your 88? If so, you have two pairs of rims, one front pair, one back pair. The difference between the two is the spacing of the rim. I would not suggest switching the rears to the fronts and vise versa. About the only thing you can do is switch the lefts for rights and vise versa.
I've posted a picture of the markings on a spare set of IROC rims that I have for my Camaro. Let me know if this helps.
