RRS camera plate for Linhof Technorama 612?

Has anyone figured out which Really Right Stuff camera plate best fits the Linhof Technorama 612 while still allowing the back to be removed? (The B24 plate is too wide and partly covers the release mechanism).

Many thanks!

I don't know, but when I was looking for a plate for my Rolleiflex SL66, I looked carefully at the full range and chose one which I then had to file some recesses in it to fit the unusual camera base. Maybe you could use the one you mentioned and drill a hole where the release is.
