87-89 vs. 90-93 bumper/fender differences?

Thanks for the replies. Great pic, Strype! That was just what I needed to visualize the difference. This also explains why my 17"'s rub a tiny bit on my 89 GT (just at full lock). Judging from these pics, the earlier Saleen kit would fit on the later cars, with some massaging, but not vice-versa. I really want to do the original Saleen kit, not the Cervinis', and I can only locate the 90-93 version. Oh well, I have it on good information that Saleen will be offering a lot of their old Fox body parts again! yeah!
