As for Black Racks $2800 is a bit rich for this mod even though a steering rack should give better steering feel.

Yep I know what your saying, but unfortunately the original boxes are getting old and many second hand boxes and pumps need reconditioning and in many cases when you strip them you will find excessive ware in the gears and housing making it impractical to recondition them. Correct me if I am wrong but the blacks racks kit comes with the power steering pump, bracket and all the bits you need to convert to power steering. If your car needs new tie rods, steering arms, drag rod, idler arm, steering column coupling etc plus the price of a box and possible reconditioning, plus the pump, brackets hoses and drive belts I reckon the price may be close to the blacks rack kit.

If you can find a good original box that's in good condition go for it, but be carful. A box that only needs a seal kit put through it and the case and gears are perfect the going price these days generally cost between $350-500.
