well what are you planning on using the dually for? i mean is it just a show thing or you just hope for more towing compasity in a bite size truck? Well if it was the first JC witney does make an adapter that alows you to bolt on 2 tires to one mounting plate. problem is unless you r are thing just show you got alot to worry about in your wheel bearings that will wear out almost 3 times as fast and the added weight of another set of tires and rims. IF its the second then just buy a diesel daul. The cost would almost equal out to about as much if not more and you wouldn't have to worry about all the problems with body flex, reinforcing the fram for the bigger axel and all your prayers that it works for more then a week. Before my acident though i did plan as a shock to show up to a few shows with the jc witney adapters on the front and the back, then remove it for dally driving. But with the big boom and crushed civic so went that dream
