I had my 66 removable hardtop re-weather stripped and the rear plexiglass window replaced. The window was all spider cracked from the sun. I bought a date coded rear window from Zip Corvette and had it drop shipped to the shop restoring my top. I got the top back and there was no date code on the window. I contracted Zip Corvette over it and I sent photos. The manufacturer said the date code was there. Well I eventually found what they called the "date code" by shining a flashlight at an angle across the face of the window. And sure enough there it was. About less than a half inch square, a very faint laser etched date code. It's basically useless and they should be embarrassed to call that thing a date code. It wouldn't have been all that bad had they cranked up the wattage on that laser etching and actually made it readable.

My question is, does anyone know where I might get a tool or something to actually brand in the date codes like they came from the factory with? I should note that this is not the code on my window but a photo of what I am looking to do. The code on my replacement window is basically invisible.


Side note: If someone is selling something advertised as "date coded" get a photo of the date code first.

 

On my March built '67, the Hardtop date code is " B and G". "B" for February and "G" for 1967 Calendar year. The stamping is very difficult to read and some letters are not very deep. With that said, I believe that the letter for the month should be in the lower left and the letter for the year should be in the upper right.

 

63's are so much easier to read.

 

Thanks for the reply. I know how to decode the window code. I am looking to make the one on mine (replacement window from Zip Corvette) readable.

How to decode wasn't my point.

 

I have a 66 hard top. To me, it looks normal. If you modify the markings you may be able to read it better but it may not look original. Hopefully, others will chime in with better advice.

 

The photo was not of what is on my window. I want the invisible one on my window to look like the photo I shared.

 

What was your point? I said the code on my replacement is not readable because it is almost invisible. I wanted to make that code more prominent. I shared a photo of what I was looking for not what I had.

 

Buy this stamp set at HF.. Heat the letters you need with propane torch, touch the plexi in the right spot.. Done

The markings are very hard to see. New ones and original ones. When I got my new window I had to call the seller to learn how to find it. Take a photo of what you have and post it here.

 

I know where it is. I already noted that. I found it after much searching and using angular lights on the surface. But the original ones were much more prominent.
