Yea what he said!!!!
I have a 71 GMC that has rear leafs... I went down to the local off-road shop and bought a set of axle saddles and welded them on the opposite side of the axle. Then you just put the axle on the opposite side of the springs. I dont know how much drop it gave me exactly but i'd say 4 inches at least....maybe more....
Here a pic of a "flip kit"

I know ive seen them for sale for our year trucks but they're expensive..... I think it cost me 20 bucks to buy my own saddles and weld them on....
Hope that helps
