I made one like that when I rebuilt the 4 speed. It does make setting the detent ball & spring very easy. I turned myself a length of bar to fit the i/d of the selector fork and then fashioned the concave ramp using an angle grinder. There's a drawing with the dimensions necessary in the red book at Fig C-30 - Page C1-24 (in actual fact it's the same for 4sp crash) - You don't need the dimple at the top of the ramp. As per Howard's photo is fine.
