i wouldnt buy them myself , at least not in the states the shipping alone is pretty high it would be cheaper to HAVE them made here (not even touching fiberglass with a 10 foot pole)
still figuring stuff out but i have an idea of making my own C&C rear axle from a single wheel axle fitted with dually hubs , i have the townasty rims so there a bit narrower , and i'm planning on a static drop with dropped spindles in front and a flip kit in the rear , im going to fit my airride stuff on a second half ton pickup i have
i might get away with the whole dually fenders and just widen the bedsides themselves cutting the wole bed along the top , the waste line and the bottom belt line and along the fender flare itself and just starting to add strips of metal and piecuts intoo the mix to pump everything out , a little like the old widened racecars , prolly going need some extra bedsides for the curved parts though
