well, they're fairly straight forward in terms of everything being the right shape, width, etc if it's a kit designed for the year, but depends on you if that = easy .... you're looking at changing brake setups and 6 lug to 5 lug, so there are still considerations that affect the entire build up
the best plan is to figure out what you really want in a finished truck and plan it as a package - if you just want an ocassional driver that's out of the ordinary, stock does the trick, if you want something that rides like a car, the modifications can be mild or extreme ... I just like a dependable, easy, workin mans truck
