I spotted this interesting cowl tag on one of the 66 Riviera's that was at the Riviera's in the Park picnic this weekend. 

I was wondering what the option codes mean.

. . . where's that Shawn fellow when you need him ?


I was hoping our '66 resident expert, JZRIV, would chime in here and decode the tag for Mike?


I'm not sure if the '66 is the same as the '65, so I didn't want to answer with incorrect info. If they are the same the "M" is not mentioned on the ROA site, so that must be different?

sean1997 thanks for the decode. This is a very well optioned Riviera and it was a very early production build!

This is the car the cowl tag belongs to. A 66 GS. I did not get any pictures of the interior.
