When it comes to those crap repops use only what you have too and leave as much of the original as you can...That part dont need replacin so leave it.
since those usually only rot on the bottom and back where the bumper is you might want to concider cutting & welding it at the moulding ...
#1: I wouldnt replace any of that American beauty with cheap chineese recycled rust panels
#2 If someone was holding a gun to my head and I had to use chineese (recycled rust) panels I'd only use just what I had too
Some people think I paid for the whole 1/4 I want the whole 1/4 put on.they are thinking they want a whole new 1/4 installed because its better when in fact the more you use the less the car is worth,its up to you to talk them out of it and educate them a little weather its your boss or the owner ...have a litte respect for these Amarican classics,dont hack one up just because someone is paying you...
