Thanks for the info,My plan now is a dropped axle,mono leafs,tube shocks,41-6 box,disc brakes and new kingpins and tierod ends. On the 41-6 boxes does it matter what size of truck it came off of. A local junkyard has a few big trucks that the doors have been closed and have all the windows and the hoods been closed,the only 1/2 ton had no windows no hood and no steering wheel so the box has probably gotten water in it and is junk. Who sells sway bars,I would like to put them on the front and back. Jeff
