I'd like to add a note or two to what John had to say above about the turbo tie rod install.
1) The big "washer" has also been called a spacer that goes between the inner tie rod end and the rack. This is a positive stop for the rack, turning left or right and keeps the inner tie rod end from hitting the bushing and snap ring, and possibly keep the pinion from trying to climb over the end teeth on the rack - to the detriment of the pinion teeth.
2) IMHO, the only thing that keeps the rack from rotating is the mating of the pinion gear to the rack, so it is, i believe critical to counterhold the rack when trying to loosen or tighten the tie rod ends. I did this by putting a wrench on the rack and counterholding that wrench in a vise, then tightening the tie rod end on the opposite end. I found it necessary to grind down the sides of an open end wrench, (1& 1/16?) to fit between the "STOP washer" and the flats on the end of the rack.
3) On my 74 coupe, the ball bearings that support the pinion in the housing, were open/UNSEALED. IHMO, this is a bad idea, because the bottom pinion bearing sits in the bottom, (lowest level) of the rack housing, so any water or wear debris is going to foul the bearing. A double sealed bearing, (both sides) is a much better idea.
While the rack was out, i installed a "quick rack and pinion". This is great on the road, but a bit stiff in parking/very low speed maneuvering.
