>I was planing on replacing my bumper on my 85' 2m4, with a 87-88 coupe >fascia, I will still have to buy new bumper absorbers to go behind it >correct?I have replaced my front bumper...I did not use a different impact piece. I just trimmed it a little around the marker lights. It is easy to do. Just mount the facia, and see where the impact piece is not right. I trimmed about a couple of inches of material off, not very much. I think I could have gotten away with just leaving it alone. Don't waste the money unless the part is free with the facia.
I did my front facia. I am not sure about the rear. But the same holds true, just try it and see if it fits ok. and trim away the excess.
