Heat Treating Axle shafts

We had this trouble on our race cars. You could shorten them enough for length, but the axle spline would bottom out on the carrier before the axle was all the way in. Good luck!

Just for giggles, I checked the spline engagement on one of my old 9" 33 spline Currie drag axles and total engagedment of the splines into the carrier was 1 3/8
