Just looked at the engine on my 1966 +4 and the suffix is ME, although the M appears to have been squeezed in between the last number and the E!
I think that the dashboard in my car was made when the car was restored some time ago, so although it has a glove box lid it doesn't give any clue as to how it left the factory.
Welcome to the forum, I'm sure that you will enjoy the car!
