Have you looked into the Warn flares. I have had a set on my '90 for almost 18yrs and the last time I had one off, there wasn't anything trapped under it other than some dust. Unlike the Bushwackers the Warn have a wheel well side that screws into the oem fender trim mounts.

More than tread lightly. Leave it like you were never there, nor anyone else.
