OK last weekend I swapped out my aluminum housing & 3rd for a steel GV unit with a 26 spline carrier from a sport. during installation, instead of just changing the passenger CV right out I just changed the 26 spline cup that goes into the axle housing with one from a X-90. Everything seemed to swap straight over no problem. The next day the guy from the shop were I did the work, said he couldn't put the 22 spline cup onto the X-90 CV saying it was too small. He didn't try hard enough to make it fit, he just called me the other day saying he thinks we made a booboo with that swap.
Anybody know if there is a difference in size ?
Thanks
