Slip Yoke for a 727?

Just went through trying to source a 7260 slip yoke for my project, Neapco has all sorts. A slip yoke for a 7290 30 spline is their part# N729-3-1932X. There are other brands, no idea country of origin on any of them anymore. One with a 1.312x 30 spline, hub diameter of 1.68 I believe you need.
