Any idea if the back doors on the XA and the XA2 are interchangeable? I've got a real nice XA2 with a crappy back and a dusty XA with a nice back I like the XA2 better so I would like to keep the improved XA2 and sell off the XA
I have only the XA so I can't really address your question. But since you have both, it seems to me that you should be able to tell just through a close examination.
They look to me to be identical. It appears that the hinge pin is just retained by a little nub on the bottom plate. If you remove the bottom plate you should be able to slide out the pin.
