got it on good authority from Cliff Clavin it was paint color
I heard from Cliff Clavin that Tubebender only ran pink on his drag cars and that he preferred Ford Pinto and AMC Pacer brands. That bracket that Roccus posted was a thru-the-windshield rear view mirror clamp that I think Tubebender designed on Autocad and had machined on a CNC machine. Unfortunately installing it cracked the windshield so it was not a million dollar spinoff from the garlic farm.
