I'm trying to code the door glass in my '69 2+2 convertible to the rear windows I picked up here on the forum!  Here's the question from the shop, if anyone can assist:

"We are preparing to get the date coding for the rest of your glass, and we have a couple of questions to send your way. The rear quarter glass that we received has 2 different date codes one AE and one AD  and like you mentioned in your email, we will be coding it with the AD to decode to March of 69. In the reference photos that we got there is an extra set of numbers 7686771103662. Is this number a reference to a part number that we need to replicate on the other windows? I am having some trouble finding what this number is in reference to, but I am continuing to investigate it."
