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?

Thanks,
SP

31 Spline axles are fine. The 35 splined axles with an ARB require the axles to be shortened, due to the large ARB cross-shaft. The note is only for 35 splined axles.
