this is my rack from my late model 86 GT with Rodney bushing being installed. I ran into that problem as well but decided to put it back together at what I thought looked right and using Rodney's instructions. Basically Ignoring the dimensions, and lined up my front tires with the rear using string, then aligned the pinion with the rack in accordance with my steering wheel position before I tightened down the column. The star key I believe had a specific turn ratio but was in the manual. Sorry don't remember from off top of my head. When I did alignment at the shop my alignment wasn't to far off, but still needed. I have also read that if your rack feels sloppy after reinstall tighten down the star key more could help. I didn't need to do that though. Hope this helped a little good luck with the overhaul.
