Another photo. Note the space for the back-swing camera part on this side of the camera breeches the ramp for the CFH--but it doesn't effect the light trap. A thicker back or a 1/2 inch wood spacer (with a 5x7 inch window) between about any 5x7 back wedded to an aluminum plate would work.
Also, the only part of the B&J back that had to be sanded off was the small top and bottom flanges. Everything else was fine as is.
