Glass Coding 1966 Rear Plexiglass (Hardtop)
Can someone tell me if the coding on the rear hardtop plexiglass is coded different than the rest of the glass. Also does anyone know what happened to the Valvoline web page for glass date codes. Thanks, Wes

The optional hardtop of acrylic has "PLEXIGLAS" trademark, a month date code, the word "Acrylic", a year date code, and an AS-4 rating. Month codes are a letter starting with "A" for January and ending with "L" for December. The year codes are "E" for 65 and "F" for 66. So, November 65 is K/E and March 66 is C/F.

The "month" code letter is to the lower left of the logo, and the "year" code letter is to the upper right of the logo. Hardtop back window date coding is completely different than for glass.
