i'd say it mostly depends on what wheel you want to run and how much you want to spend/work. going to 5 lug in the front is pretty easy. but going to 5 in the rear is a bit more involved as the axles must be swapped along with the drums, or the entire rearend must be replaced with a later model. of you want some 5 spoke wheels lite cragars or torque thrusts then you almost have to have 5.
