Power Hydraulic System, bleeder screw thread size and pitch when removing SLS

New to the world of Jaguars
I’m working on my 88 XJ40 to remove the SLS. In lieu of installing the bleeder screw (CAC 8293), I just want to install a plug into the valve port. Does anyone know the thread size and pitch I would need?

It’s an M12 x 1.0

Thank you kind sir! This will keep me moving.
