there is apparently some differences in OD and maybe splines etc on slant 904's? I seem to have wear on U joint yoke spline on driveshaft (female) side ,fit is VERY loose. is this common?? I had a later slant/904 yoke, but OD of yoke will not pass seal.

This 904 output spline , which i believe is stock, although rebuilt, is about 1.105 t0 1.110 OD , with 26 splines. i am looking for this part. local driveshaft shop cannot find one, they also came up with bigger OD.

Anyone who can help, or comment on this, or wear, thank you in advance. ..and i'd like to buy one...
