I have a 14 bolt dually axle hanging out, taunghting me to go under my suburban. Only problem is I don't think there is enough room to move the spring perches out far enough to make it fit. Has anyone done this swap on a 1/2 ton or 3/4 ton truck? Do you know of any other problems I might run into like the tires hitting the frame? I still have a 14 bolt semi floater also. Could I use the drums and backing plates from the dually axle on the semi floater so I can run the dually set up? Just think it would be bad ass to drive a dually diesel burban around. Thanks for your help. Mike You call that dirty!?
