904 slip yoke

I've got a 7290 904 slip yoke from Mopar Performance. It's not a billet piece looks like a factory type yoke. I don't think they offer them anymore though.

But to answer your question there is two different spline angles. I've seen the larger joint yoke with a 26 spline slip but the angle of the splines were changed some time ago. In fact I have one of them in the garage somewhere.
