unless your a pretty decent machinest i would just buy it your steering isnt something to be messing around with. and no you dont modify your stock parts to make crossover you buy new ones.
you will need either a 2wd steering box or just the sector shaft out of a 2wd
a pitman arm
you need a passenger side flat top knuckle and it needs to be machined for studs and a steering arm
then a crossover steering arm
a draglink
and a couple TRE's
