The 9" is very strong. The cost of having it cut to fit under your Jeep will be around $160. Axleshafts will be another $300 (for Mosers). Spring perches and all other brackets $260 plus labor to weld them on, est. $150/$200, gearing , depending if you want a locker, anywhere from $400 to $800. Then installing the axle, possibly reusing all the D35 braking equipment. You are looking around $2000. HTH
