Picked up a free Spin A Card today. The PO had it in a trailer and it fell over smashing the back box,miraculously the backglass survived! Its all there and I intend to restore it,problem is this was a unique back box shape (anybody have one?).Then I noticed a broken score reel contact board, is this repairable? Otherwise, play field is in what I consider great condition for 70,000 plays. Pop bumper protectors were installed before damage,and plastics are all in good shape. A lot of units under the play field I don't know a lot about but in your opinion is this machine worthy?
