Using A2 rear Disks upside down on A1 Drum upgrade.

[ralexander03@snet.net (Rick Alexander)]

My understanding is that the A2 and A3 mount the same way but that the
problems were not solved until the A3 which is why they are the desirable
units to get for an upgrade. But then again... you have the A2's
