A heat gun, which you can get for about $20 is the key. You could rap your aluminum bat with duck tape and just be easy as you go. Get the part of the fender you are going to work on nice and hot (without burning the paint) and just do your thing. I got the portion of the fender which was cutting into my tire rolled good. I may hear a scrape if my air shocks go down in pressure but I know it is not cutting into my tires, just rubbing them. I just acquired a 9" rearend whuch I'm rebuilding to put in my Mustang WHen I get this accomplished I want to order new rear leaf springs. I am going to go from 4 to 5 leafs. Mustang plus makes a 'Street heat kit' that stiffens up the rear.
