Anyone know how many splines there are on the steering box input shaft on a 1975 Coupe with power steering?

I am planning on installing a tilt steering column and need to know which adapter to order.

One parts site lists it as 25 splines, but my rough count seems to be more than that. . .  The shaft is 3/4 inch in diameter.

I believe they are 30 spline, with a 3/4" shaft. It would prolly be best to get yours off and count them, to be sure you order the correct replacement. 👍

I have an old rag joint that I could roughly count the splines, and it does look like 30 splines.
Thanks!
