shift kit - gear changes are crisper/ quicker and the auto can still change gears by itself
manual valve body - everytime you need to change gears, you need to move the stick (it will not change by itself)
i like the white on white but depends on the rim. need polished lip and dish
check out INASNT's 33 in the for sale section. looks awesome!
