The best way to hang one is as follows:
Find a Pinball machine of the same type as your backglass, that is missing the glass and buy the machine and hang it in there... 
or 2. Find someone who has a machine with a poor or missing backglass and install it there... 
Good ides but have two many machines and backglass and no wear to put them.
Had a cabinet maker come over on Monday and look likes were going the timber look.Should be able to the use the same method to get them in and out as with a pinball, with not to much trouble.Just got to get them out and measure them all up hoping that all the size are the same or very close so he can get started.Found two more i forgot i had buried in the corner with all the other stuff.
Will post some pictures when i get started, hopeful should look sweet.
