Dumb ***

I was cleaning up my '65 Formula S wiring harness and came to the map light, which had a bulb base stuck in it, but the glass was broken/gone. After a short struggle with a pair of needle nose pliers, I was able to push down and twist the brass base and pull it out.

The lamp I pulled out was a single terminal #67. The map light has a twin terminal socket (yellow and pink wires) and requires a #90 double post lamp. Duhhhhhhhhhhhhh.
