GTS front suspension users, I need a measurement

Just curious, but are you concerned about where the rack sits or where the actual tie rod passes through, the reason I ask is because the rack can be mounted right to the frame, or you can put different spacers in to move the rack back, I prefer it to be back as far as possible, to keep the tie rods as straight as possible with the rack shaft, some oil pans don't allow that, also, is it an early A or late A?
Thanks
Carl
