Topic: Outside mirror question.

[austexstang]

The outside mirrors, LH remote & RH non-remote, on my 6/65 Dearborn Coupe are reproductions and I want to replace them with OE mirrors.  My question: is the glass date coded?  I've seen some original Rotundas that appear to have a date code etched at the 12 o'clock position of the glass.  Thanks.
