The Arcatech Arca-Type Quick Release Plate works for the RZ67 and is sturdy, well constructed.
Does the job

Fits my Mamiya 645 perfectly. I especially like the two pins that keep the plate from rotating. The plate is large enough that the camera (without handgrip, with 80mm f/2.8 lens) doesn't wobble when placed on a flat surface, unlike many plates I've used with other cameras. But it's small enough that it doesn't add significant weight or size to the camera. Goldielocks!

question
Am I correct in thinking that this will work with a Mamiya 645 Pro/Pro TL bodies?
If the bottom of your camera has 2 pin holes on each side of the tripod mount that are 2 inches apart...yes it will work.

Can I use this on a Mamiya C330f?
Can I use this on a Mamiya C330f?
We have not checked this camera but I can tell you that the pins on the wings of this plate are 2 inches apart. If you measure the distance of the pin holes on each side of your tripod mount and they are also 2 inches apart....yes it will work.
