56-7 Hardtops Original Glass Date Survey

[Gary C.]

Am interested in obtaining date code format for original side and rear window plexiglass on 1956 and 1957 hardtops. Thank you in advance for your response. Gary....

Please let me know what format your 1956-7 ORIGINAL plexiglass follows:
1 - side and rear window glass; Month Year two digit "7 56"
2 - side and rear window glass; Month Year single digit "7 6"
3 - side window glass only; Month Year two digit "7 56"
4 - side window glass only; Month Year single digit "7 6"
5 - rear window glass only; Month Year two digit "7 56"
6 - rear window glass only; Month dash Year two digit "7-56"
7 - rear window glass only; Month Year single digit "7 6"
p.s. include any other date formats not listed

Gary,

Here's what I got.

Right side window A S 4 5 7 (on inside of plexiglas)
Left side window A S 4 5 7 ( on outside of plexiglas)

Rear window AS-4 1-59 ( on outside of plexiglass)
This does not seem to fit dates and is most likely a replacement but it sure does not look like this top has ever been apart.

Hope this helps.

You could find different dates on most any year top I bought rear and side windows in the 70's having the 70's date code , I think they dated the parts when they were made.

Gary,

This is what I have on the hardtop for my 57 #3029.

Side glass: AS-4 7 6
Rear glass: AS-4 8(?) 6(?)

I can't read the the last two numbers very well.

Mike, thanks. Give the rear glass another good look if you can and let us know. Have the side glass date format pretty well nailed down. Some direct responses I've received on other 1957 hardtops have a two digit date code on their rear windows in this format " - 57"; i.e. space dash space two digit year. Thanks, Gary....

Mike, thanks for the photo. Getting closer to determining when the change over occurred in the rear window date code format. Gary....
