Exactly... and thanks John, it took me a few years but I'm learning. (check the date on the first post in this thread)

As the chart on page one details a Cuda (BS VIN) with G36, in any of the 6 specified colors should have come std with the color keyed grille.

I want to record as many as I can to see if they fall off at a certain date possibly due to a supply issue (as they say 71's did when a delivery truck rolled over)

I also actually found a relocated California 72 TB3 V21 here, it has aftermarket mirrors and argent grille but upon inspection appears to have had a minor front end collision (If I recall corrctly it had a factory replacement P/N stamped hood, I know the hood latch support was not painted) it's a G36 car built 8-71 so I'd say it had the color keyed grille.
