Newport glove compartment lock/catch

Hi all, a few weeks ago I was made a too attractive offer for my 67 Fury III hardtop so it went to a new home.

I am now the proud owner of a 76 Newport, 2dr with a 400 and 4 barrel.
I got it with only 1 key which fits roughly in the ignition but nowhere else, I can get new locks etc from rockauto so that's no problem, but the glovebox lock/catch is broken and I haven't seen one for sale anywhere, anyone got a source?
