I could be wrong (it has happened :D) but I am under the impression no 8.75 yokes fit any 8.25 pinion shafts.
Is that wrong?
I had the driveshaft shop look and he didn't find any 8.25 yokes for a 7290 joint with 10 splines either.
(27 and 29) splines for the 8.25 are available though, because Jeep uses them.
