FFI steering box install - now centering and adjustment questions

[cougs]

Hi all-

I am instaling a FirmFeel stage2 box and their close ration pitman arm.  I have a couple questions regarding centering.

1. the pitman arm doesn't have provisions on the spline for centering or postioning so I "eyeballed" it assuming that the steering box comes pre-centered.  Do I have a probem if I missed the center by a couple teeth? 
2. Re-attaching the steering shaft:  I can't tell....does the spline on steering shaft need to go on the steering box in a certain position?

I've always eyeballed it. You can run the box through its range of motion to find center, then install the pitman. Don't tighten it down and install it somewhat loose. Install the column, also loosely, and again check range of motion. If you have everything where you like it, you don't run in to any issues from left to right, then tighten them down.

The steering box input shaft has one missing spline which mates to a missing spline on the coupler.

Mine has 4, 90 degrees apart.... I would not imagine it would be hard to find the right one? I'm installing a stage III soon.

Both of these should have master splines, may want to buy a shop manual.
