I know I am not supposed to be running a Ford rear under my D50 but that is what is under it. I broke a axle the last time I was at the track and I need to figure out what spline to go with. I was running after market 28 spline. I need to upgrade, what spline count would you run 30,31,33 or 35. I only have about a month to get back track ready.

If you have to buy axles and spool anyway, go to 35 and be done.

Just be aware that 35 spline will require a 3.25" bore case. If you have a 3.062" bore case, you can either run 33 spline axles, or go with a Mark Williams spool. The spool is longer, so your axles will be slightly shorter. The other option will be searching through the Timken catalogue and finding a different bearing.
Secondly, do you have the large or small axle bearing? Small bearing will require new housing ends

Though you can get a 33 or i think also a 35 into a 3.0 case you will shortly after break the case as the bearing is so narrow/small . Sell your current centre and upgrade while you can sell it . Tex
