I have the Motive Pressure bleeder, and it works great on the MB. Has a cap that screws onto the MC reservoir.
I used the Mity Vac on my Datsun PU only because the universal adaptor I have for the Motive leaked.

and there is no way the Motive will fit onto the tiny Clutch MC. The Mity Vac worked ok, but was more work and time.
The biggest problem I had with the MV was air being sucked around the bleed screw into my discharge container.
