Heres another FYI.

This is a picture of the long, 3 shorts and the early. You can see the spline size in the top (long) and 2nd (short) are the same power steering size (approx .600"). So the difference in the length wasn't manual and power as some have suggested in other online discussions (there is SO MUCH bad information online).

The 3rd and bottom are manual steering. The spline is approx .700"
