'56 Country Sedan Rear License Plate Holder Assembly

[tsanborn]

This is probably a futile search but I thought I'd ask. I was in a hit and run accident in my '56 Ford Country Sedan wagon that damaged my rear tailgate. Repairs are complete with the exception of the rear license plate holder assembly. For clarity, this mechanism swings the license plate away from the tailgate when it's lowered. There is a cast metal base with two "ears" that hold the pin on which the license plate assembly rotates. These pins broke off with the accident. I've tried to epoxy the pins back into place without success. I have drilled the back of the ears and inserted small screws attached to a new backing plate with similar results. I'm stumped and hoping someone might have a suggestion. If anyone can suggest where I might find a replacement, I'd be most grateful (and amazed!). I know I'm looking for unobtainium but thought it would be worth asking. Pictures attached if what I'm trying to describe isn't clear. Happy 4th to all!
