C3 Glass date coding

[Eric F.]

I have differing date codes on my side glass. The driver side is obviously a replacement and I'm having a heck of a time adjusting it to the new soft top. Is there a way to determine if it was intended for a coupe or a convertible by deciphering the numbers? If so, does anyone know how on replacement glass?

The passenger side glass is marked M74, which the TIMJG states is for a coupe, and it was easy to adjust. I'm wondering if the TIMJG meant to list the M74 code for a convertible and the M75 code for a coupe. Does anyone know?

Thanks in advance.

Eric,

Coupe glass on the rear edge is practically straight. Convertible glass rear edge has quite a noticeable angle (forward).

C-3 coupe glass will not fit a convertible the shape of the top rear on a coupe is 90 degrees. Convertible glass is much more than 90 degrees I would guess at least 110 degrees. Good luck with the adjustment.
