Are the 6" lifts the same as the 4" just taller. I have heard people talk about the crossmember being in the way for a 6" lift. Also I was wanting to switch the tranny for a 5 speed with hi/low? Do some of the 82-84 wagons have that set-up? Do you think the rear-end from one of them is better than what I have in there? (just the stock gen I)
