Loose inserts are common with this title. They aren't hard to find either.

$250 for a new backglass and you are still only 250 into the game.

I don't know that I'd bother with full blown restoration but that's not my thing. It looks like it's in nice shape inside and that's a pretty simple/easy game to get working mechanically. The Iron Workers local sticker is also badass.

I'd say save it, unless you really need a parts machine.

If it were me it would probably be stripped for a parts machine - I don't have space for a major project like that but maybe you do.
