9 1/4" Axle Swap?
Moser sells new 8 3/4" rear housing ends (weld on). If you really wanna use 9 1/4" differential, you can weld those housing ends to the 9 1/4" Diff. That way you can eliminate the c-clips all together. Then all you need to do is get custom length 31 spline axles ( 8 3/4" where 30 spline) .
