These are the numbers off a 5 blade 4 flat rivits fan blade. On each fan blade the numbers H 8 0 14017704 Pat.4,050,847 Also There is a AD stamped on the clutch assembly. What does this go to?
Mirror number 2 DMI7? These are on a 1968 Camaro which I think is a BB car.

Mirror is Feb 67 built by Donnely Mirror Inc.

Strange for a square mirror to have an early 1967 date. How about the fan blade?

Does anyone know if square mirrors were used on any other GM product prior to '68 and phased into Camaro production?
Seems to me I saw square ones on an Old's or something earlier.
