The yoke feels funny when I try to insert it. Come to find out it has 26 splines and the stock unit has 25 splines. I checked another 904 slip yoke and it has 25 splines. I also checked a 727 slip yoke and it has 29 splines. Did mopar screw up? Did any one else have this problem? What did you do?

It will go on but it spins over the output shaft of the trans. 11.02 @ 120 mph - Slant 6 & Turbo http://www.youtube.com/watch?v=EAxRmoDgsdY Chassis Dyno http://www.youtube.com/watch?v=wd6hFGzLJMc

The 25 and 29-spline reference is to slip yokes with one spline removed but they are still for 26 and 30-spline shafts. There have been many complaints that the newer slip yokes won't fit their respective shafts, they're just made wrong. The INTERNET, the MISinformation superhighway

No idea where it was made. Drive shaft was built a few months ago so the box is gone. 11.02 @ 120 mph - Slant 6 & Turbo http://www.youtube.com/watch?v=EAxRmoDgsdY Chassis Dyno http://www.youtube.com/watch?v=wd6hFGzLJMc
