Why haven't you contacted Citsa directly? - They're all over Mexico and the QR code is screened onto your windshield. Here's one of many locations:
Open ⋅ Closes 5:30 PM
English side of the website: http://www.citsa.com.mx/en/index.html

Email : mtrueba@citsa.com.mx
I scanned the QR code on your windshield and it took me to the Cista site and if you click on the American flag at the top right of the page it comes up in English (whew!) But you'll still have to either email or telephone them. Don't be afraid of the language difference - LOTS of people outside of the US speak lovely English if you're polite to them.
Or you can try the phone number above and ask "
¿Puedo hablar con alguien en inglés, por favor?(May I please speak with someone in English?). Shouldn't be a problem for them, I'm certain.The screened info on your old windscreen should give them enough info to get you a new one of the same model and you can send the photo to them from your phone (It worked for me to get me to their site).
I don't know how many variations they have to that particular model, so you may have to tell them it is for a replica, but the info on the old windshield should be enough for them to find one for you. If Carey Hines could ship me four new windshields from Indiana to South Carolina together and get them there intact, then Citsa can get one to you from Mexico - I'm SURE that they ship them safely all the time. Probably have their version of the top and bottom rubber gaskets, too, unless yours are in good shape.
