Excellent machine work one detail you could use in the future when I do this conversion for spider gears I use the original Ford banjo 12 tooth gears. To make them mesh correctly with the side gears I machine the rear surface of the side gears the required amount to allow the assembly to rotate correct.

I know 12 tooth gears.
These gears are 10 tooth gears, they are more resistant for power and develop more speed.
Powered flathead needs more development
Thanks
