Hello I have ID'd my housing as a 76-77 11X21/4. I will be running an ARB AIR locker and see the following note: NOTE: please choose 35 W/ARB if you plan to run an ARB air locker. Can I get 31 spline that will work with an ARB since I will not be upgrading the housing? <br><br>Thanks,<br>SP View answer
