You might try a Mamiya 645 Super body. They have the necessary mirror lock up and tend to sell quite inexpensively on Ebay and at KEH (there is a bargain grade one there now for $126.00 US). They also have both an electronically controlled shutter, and an electromagnetic shutter release (the release may be important, because finding a way to actually release the shutter when it is inside your view camera may be important ).
I have two Super bodies. When I get home later today, I'll make some measurements of the throat diameter, body depth, etc. and report back.
