Hello, I have a simple and quick question for y'all, my 84' Chevys bumpers bent, but I have an 89 GMC parts truck, do you think that I could just bolt on the bumper off the 89' onto the 84'? Do they have the same mounting brackets and bolt holes? I'd hate to take it off just to find out it doesn't fit, BC its like 100 degrees out today and I don't wanna do all that work 4 nothing, thanks. (Its the rear bumper BTW)
