6 inch lift kit help!!

[Jaredchevyk20]

I'm picking up a 6 inch lift kit tonight. The guy says its a superlift full spring set up. I thought superlift only sold front springs and rear blocks? I know they are coming off of a swb k10 with 3/4 ton axles, maybe the rears are stock k20 springs with add a leafs? Im trying to put them on a completely stock 1987 chevy v10 Lwb. What will i need to grab from him? All 4 springs, shocks, steering arm, pitman arm, What else? also do you think i will have driveshaft problems? I have a 700r4 tranny and im not sure of the transfer case. Thanks
