Well, last spring I finshed the re-chevy swap. PO had chevys but my wheel base was almost 134" he also used double shackels, only a 2 leaf pack. End resultwas bad turning rad, ĊĊĊĊty ride, with lots of axle rap. I shorted the WB(used sky's chevy kit), I made a flatbed over the summer. I found alot wrong with the PO's SAS, (he had rears up front) I just put in marlin's 4" springs and drop hanger. Sits uneven know, and front axle is too far forward. Plan on roger brown'sSpring Relocation Plates and pulling a leaf out of the marlin pack.
