Backglass - We will have new ones in stock as soon as CPR re-run them in the Mirrored format. At the moment, only the "budget" or non mirrored are available. We are also ordering the FG plastic Set.
Backbox - Call guys like Chris from
@pinballmedic or Bill
@billxixix - They might have a parted out headbox that you can use. Also - worth checking if Stu at Platinum Pinball has one that is already made up.
