Looking for Bally Mariner backbox components

I recently picked up an old Mariner cabinet without a backbox. I'm looking to restore and customize it, but need the backbox components. The backglass isn't so much of an issue, or even the wooden box itself, as I can probably build those, but the inner workings and mechanisms I definitely do need. If you have a complete backbox, I would be more interested (depending on location), but as shipping would probably be prohibitively expensive, I'd be happy with just the inner workings, so long as they're functional.

It can also be arranged to meet at Pinfest in Allentown this May, rather than shipping an entire backbox out.
