To determine the spline size of a component (rack and pinion, steering column, and steering box), measure the outside diameter and count the number of splines. If there is a flat spot on the shaft and some of the splines are missing, count halfway around where there are splines and double that number. We need to know how many teeth are in a theoretical full circle.

Available U-joint combinations are:

Smooth bore on both ends
Smooth bore and Splined or Double D
Splined and/or Double D on each end
