Guidance System Finbox Wanted 11.5"

I’m looking to find a long Guidace System Finbox (11.5") for a board I’m restoring.  It would have to come out of a sacrificial beater because I doubt if there’s ant NOS out there. Any leads woould be appreciated.  

The one in the picture is only an example, it’s in another board I’m bringing back to life and not quite bad enough to sacrifice for the box.

 

Hey Gene, I have one for you, let me know how you want to arrange a meet. im in pasadena , -ben 

Thanks Ben! Just PM’ed you.
