the way i read the specs o the input shaft from MasterPro, there are 25 or 26 spline per their website. assuming that is not counting the flat spot on the shaft.

Wanting to order the CSS-1DD730 by CPP which is the 3/4-30 spline.
just want to verify this.

i figured it out.
The steering gear box has 25 splines showing. the flat spot on the shaft accounts for about 5. thus a 30 spline rag joint will work. i had to process this for a moment.
