[Jukebox-list] Rock-Ola bubbler light diffuser

Does anyone here have this box that they can measure what the plastic above the speaker grill? It's about 3"x 10". I was being brain dead when I was there and forgot to measure it. (it is now dark brown and no light reaches the speaker area) I did a quick check at Victory glass and they don't sell one (probably because it's so simple to make).

If I don't get the size I can bring some *special* light diffuser material that I got for free and can cut with scissors!!! (It's one of the plastic layers of a trashed LED TV screen.) ;) Handy stuff to have around, but I would rather use some plexiglass.
