Fortunatly for me it's pretty easy cause I'm a sheet metal worker, I just marked up about 2" all the way around the inside lip of the wells (front and rear) cut it out with tin snips, leaving about 1/2 to 3/4 of an inch of metal showing below the line, then I bent the wells in with pliers to the line, and SLOWLY hit around the bends with a hammer so they would form. If ya really wanna see, I can post some close-ups of my and OFFRODN's wheel wells. I done em both, but his was more of a pain in the tucass, cause I guess they changed rear wheel tub styles between 85-86
