My wife's 41 GMC

I didn't notice the cable operated signal; I'll go back and look.

You can (probably) find that floor mat - as well as the Huck brake wheel cylinder rebuild kits at Jim Carter's, Chev's of the 40's, or Bowtie Bits. Make sure you post threads with pictures when you do that work!

EDIT: Oh, now I see it. It's the old semifore type signal arm that comes out from the flat bed head wall. Very cool. Do you know if that was original and he restored it, or did he think it up on his own? Cool. THat would be waay cool on a lowered street type COE to give it more of a connection to its original use.
