I have found a set of 15 inch (yes i said 15 inch NOT 16) 89 Iroc Rims. Question to the board - guy said the backspace is the same front and back..?? True?? - are they marked front and rear on the rims like others and can anyone pls tell me the true backspace?

Thanks for a quick response - not much time left for the auction to close... and thank you Third Gen site for a great resource!
