From my understanding, the Ford 9" 28 spline is the same as the Monty 28 spline rear.
So technically a Ford mini spool or possibly lunch box locker would work ?

My main concern that I have yet to find an answer to, is the cross shaft dia.
For has a 3/4" shaft. Is that the same as the Monty ?

And if this is all true why can't I find any info on anyone doing this.
