Thanks,
I couldn't find the MA suffix on the sites I was looking at. Probably not from a corvette, with the two barrel. That's what I was thinking also.
I came up with it was made in Flint May of 62.
I did meet Chuck Yeager a few times at the air shows around here, very nice man to chat with. Last time I saw him was at the air show at Forbes field in Topeka Kansas.
