There are two different types, more than likely due to supply at time of manufacture.

Seeing as you have a a manual steering rack (I may be interested in that) either of the power steering units would work. Take everthing from the donor car, from the tie rods up...don't forget the pully on the engine....belt(s), hoses, mounting rack, etc.

If your brick has AC, get the pully from the donor brick AC (should take two belts). Hoses and belts may need to be replaced....you now have them to use as a reference. Also, try to save all bolts, washers and nuts....a pain to try and replace not knowing sizes.

You may also want to take pics so you have a guide as to how it was mounted and connected.

Let me know what you want for the manual rack. Have fun.
