Got the new steering rack, tie rods, reservoir and pump in. In this case the AAE replacement was a LUK pump instead of the ZF which was one I had. I am not sure if that will always be the case or if they will reman what they get back. I see the early e36s came with either a ZF or LUK pump. The later ones appear to all be ZF without the threaded housing but the pump itself seemed to be the same as earlier ZF, same mounting holes and pumping pressure by both.
Also I replaced the E34 solid coupler with a new stock rubber one. Feels much better for street driving, I'll take the preciseness hit.
Did the work at BlueBimma's house. His 6.0LS behind mine with N54 swap in progress for red.
