I recently boubht a 88 f150 5.0. it has an aftermarket drop bumper on it, but the previous owner spray painted over the tow rating. I tried to use goof off to see if i could get the paint off the sticker, but couldn't. Anybody know the low end rating on these bumpers. It conects to the frame with four bolts(two on each side) and is welded at the bumper. This is probably a 4-6" drop chrome plated bumper. Thanks for any help.
