What is this tool thread?

F is idle speed adjuster...D looks like E clip...E looks like AC line disconnect...A could be door panel clip.

Wow, that was quick! Here's another angle- note the rotary wear pattern on the left side of the Vixen, also the similar pattern on the right side of the "R. L. Day Los Angeles" tool beneath it. I thought it looked like the Day tool was being used to loosen/tighten something threaded. I guess I'll have to start researching e-clip tools.
