Hi, when I bought my 42 1/2 ton Chevy pickup it came with an extra drivers side front fender that was in better shape than the one on the truck and I never paid much attention to it, but it looked a little different to me, until I what to put it on and it is, it goes in more in the front,and the support bracket did not fit is the 42-46 1/2 ton fenders different than the 3/4 and 1 ton trucks
