I've got a N90s with the vertical grip. I'm having a problem getting the stroboframe Anti-Twist plate for this configuration to fit the camera and bracket. The Stroboframe part number is 300-BE1. If I install the plate and screw my "Quickflip" bracket the plate is about 1/4" off the back of the vertical grip. It is the pins in the plate that prevent the camera body (vertical grip) and bracket from nesting all together. Any help would be appreciated!! Thanks, Mike
