isn't too bad really. the rears pretty close to centered, and the front is driverside drop, so you shouldn't have any drive shaft/tcase issues really. its really all in how you set them up as to how much itll cost. rear is pretty cheap. leaf perches/shock mounts gears/locker, and install. probably will end up being around 800 including the price of the axle
fronts can be a little trickier because theres so many ways of doing them. i went with a TNT truss/mount system which was 400 bucks, but well worth it IMO. all i had to do was sit it on top of the axle and weld it on. no measuring, or fabbing parts. then theres the gears, locker, rebuilding the seals, etc etc. ive got around 1200 in my front, and thats on stock shafts. by the time i put alloys, and longfields in it itll probably be close to 2k
