Are all the pictures of the logo taken of same piece of glass (in other words are they all a windshield), or could one be a windshield and the others door or rear glass?
I'm no expert on LOF markings, but I do know that laminated glass is usually used for windshields because it's stronger, while tempered glass is used for side glass (likely because it's cheaper?). I'm pretty sure this has been the case since the early 60's. I don't think it's common to have the "M" code on a windshield, but it's usually found on door glass, so maybe the judging manual's photo of the laminated logo is of a windshield, and the logo sample photo is of the tempered glass logo is a door glass?
As far as the "M74", I've been told it represents a code to identify things like the thickness of the glass, the glass structure, shading etc. I don't know if it was used in the early 60's, but it is quite common on late 60's auto glass. The LOF date code was not at the bottom of the logo (where the "M74" is in the first photo), but instead is always besides the LOF logo, opposite of the "AS1".
This is about all I know about auto glass, and any conclusions I came to are just guesses.
It looks like 65hihp beat me in by a couple minutes, and more or less confirmed what I was guessing.

Great points... the picture on the AutoCity inert on the windshield could actually be for a side glass in error. (of course, it doesnt read like my side glass, either)

Your first post picture must be side glass. Windshields are all laminated while side glass is tempered .
Laminated side glass is only available on some luxury makes.
Looks great. I am curious though I started a thread about Precision rubber products having a great tutorial video on removing and reinstalling a 63-67 windshield. Their web site www. prp.com by application shows WBL-D636 for the coupe gasket without trim groove, so I called and spoke with support to ask what without trim groove meant and was told they don't make a gasket that fits the 63-67 coupes. I see in your kit a precision gasket WBL-D636 Precision. If it's not asking too much, would you share with us how installation goes, because in the video it came out great. In the video not sure if they reinstalled same glass. There have been several posts about either the glass or the gasket being too thick causing problems with reinstalling the trim. I have heard nothing but good things about Auto City Glass and wishing you great success with your project. Hope to hear back. Thanks.
Update I just called and spoke with the technical person at Precision and the gasket is correct for the car the description without trim groove is irrelevant, it's meant for applications with the press in trim around windshield.
Correct Windshield markings
