i am looking at buy some fabtech control arms and coils off a guy (for a 3.5" perf. kit) and that's all he has. what else will i need? i'm guessing lift blocks (which the 4X4 store should have but i'm checking anyway) and also i'm getting new shocks. do i need anything else, i'm going to have the 4X4 shop install it, so i'm guessing they could come up with some of the little stuff, i just wanted to make sure i had most of the components (all the major ones). thanks a lot guys.
