AZspidey, since you live in AZ you may want to check out Apache Reclamation if you have not heard of it already. AR is an electronics junkyard. I went there for stuff since '85. I was able to find many GB parts there. They had(bought them out) a crapload of the vintage engraved TOS phaser dials as well. I don't know if they have the part you are looking for in this thread but it's a cool place to check out on a weekend. They have the 2 front rooms and the huge back room. Then there is the lot outside as well. Not the kind of place that you can call and as if they have what you need. More of a see what they have.
