Hot tank and sand blast that cracked flimsy K-member. Weld that up too along with the LCA's. Not everyone welds so that could be added to the cost and no welding required for a coilover kit. $$$
Borgeson box for a full tilt torsion bar suspension adds $1380. So add $604 if you want power steering (subtracting the cost of a 16:1 man. box). If you want any kind of power steering that adds to the cost. Not everyone wants to turn wide *** front tires with even a 16:1 manual box. A manual rack does as good a job as a power box.
