I just put a new gear in and had a new drive shaft made as well. I used the Mopar 904-7290 slip yoke P5007410. 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?

Thanks
