Mounting a Calumet 4x5 monorail to a Manfrotto Tripod

[ac12]

For a 4x5 monorail is the 1/4x20 tripod screw adequate or should I use the 3/8 socket w a 3/8" screw?

The latter. And don't use a quick release plate, I've yet to find one that doesn't induce a bit of wobble.

Unfortunately the Bogen head has a QR plate.
