Received a Bally solid state Evel Knievel backglass into the shop for restoration. Note this is a mirrored glass. We were able to use the original glass by screen washing it, and then re-printing on the original mirrored glass, maintaining that look. But if your glass is completely missing, we substitute gray shading for the original mirroring on a new piece of tempered glass. Check out the before and after pictures below.
