#57 Bulb Gauge Cluster Socket

I've never known the official term for this part, so I got that going for me. :wideyed:
My '66 Fury VIP has all but 1 of these and I have a small boat load of #57 bulbs, so I don't want to upgrade to the "dagger" style of later years.
Anyone have a couple they want to part with?
Or know the proper term to search for a vendor who still sells them?
(I know I said I need one. I'd like to have a spare if possible)
