My interior light bezel and my voltage regulator are put on with a funny looking screwdriver pattern....it looks like a small figure eight shape. My truck is a '51, and the parts are original. Today I started to take out some cabinets that was in a 1970's trailer house, and the same pattern is used! What is that "screwdriver" shape called?! THANKS!!!
