The two grooves on the input shaft make it a M20.

Just referring to how the seller describes it in the listing Paul - it's been rebuilt so I took it they used close ratio gearsets. Maybe it's still got wide ratio gears.
No way to tell if it was an M20 or M21 originally. But it definitely has an M20 input and cluster shaft in it now.
