Default windshield date codes

I have found the windshield date code list in the search bar, but what lead time would have been normal for our 1971 coupe? How far ahead of the car`s build date should the glass be typically?

The NCRS considers up to 6 months as acceptable, but 1 to 3 months is more typical.

As with most dates on a Corvette, all of this is quite subjective.

My 81, built in early October 1981, has a windshield dated Sept 81, left door glass dated July 81, and the right door glass and rear window are both dated August 81. The glass t-tops are both dated May 81. I've owned the car since new, and all of the glass is original to the car.

Where do you find these glass dates? I don't remember ever seeing anything etched in my windows. Then again, I wasn't really looking. Just curious.

No etching involved. Check all the glass - each will have a silkscreened block with manufacturer's logo and date codes. Ditto for glass tops.

Actually, the NCRS accepts up to a year for glass.

We`re not planning to have the car judged, but for only a hundred bucks difference between a correct dated, or non-dated glass, it couldn`t hurt the value of the car to have the right one in there. And considering the amount of money we`re going to have to dump into this heap.... uhh, I mean.... lovingly embellish on this valuable classic... a hundred bucks is nothing!

Hi,
I believe the glass WAS etched with the mfg. logo and date code using a stencil.
I think it was the Astro Ventilation label that was silk-screened.
This is the windshield logo and date code from my 71. It's in the lower right hand corner; etched on the outside but read from the inside.
VT is December 1970 for a mid-January 1971 built car.
Regards,
Alan
