Be very careful with dropping the bed - I've seen too many Graphics with ruined rear rails where someone either dropped the bed or tried to close the camera without properly racking the bed all the way back. If you feel more than a little resistance when lifting the bed back up or when closing it, something's wrong.
As for the lensboard, the one for a Pacemaker and the one for an Anny are very different. Dimensions are slightly different but also, the Pacemaker has a thin sheetmetal board with a light trap groove on the front standard to match, and it has rounded corners. There is an adpter made for the Anny and GV which will allow you to mount a 4x5 Pacemaker board.
