I had the Chrysler machine shop EDM the teeth into the center, then I cut a 1.625 hex into the face which engages on the face of the housing. We designed the shift fork to use 4-48 thread allen heads turned down on the ends to .08 which ride in a .084 groove in the shift ring. The pins are spaced 120 degrees apart and suspend the shift ring on centerline. We are using the 1/2" stoke Bimba cylinders for shift actuation. One other item we had to address was the radial load the drivetrain applied to the output. So we are now using .500 Timken Tappered roller bearings to keep the shaft from wearing out the gearset.

now if only Chrysler would put that kind of engineering into their cars
