Converting my 94 2500 to 17" DRW and am trying to decide on rear fenders. I saw a picture of a 2nd gen truck with 3rd gen Megacab rear fenders on it, but can't find any info on what had to be done. I'm sure there was some mods to the fenders involved. Anyone try this or know what all it involves before I go any farther? Trying to find a cheap set (or even just 1) that may have some damage, but no luck so far.
