OK, I think I could order Superlift's 6-inch lift kit (K462), but can anyone confirm that for a 1978 Chevy 1-ton Crew-Cab Pick-up w/350 auto? Also, what if I want to go higher? Can I do a body lift? What about add-a-leafs in addition to the 6-inch kit? What about steerinf geometry? How do you guys do it anyway?
