    It looks like it has been repaired before and modified with a larger square base. I recommend to lightly sand the glass and base with a dremel grinder stone and use a two komponent epoxy glue.

    I have found that Loctite 233841 Super Glass Glue works just fine.

    Loctitie 326 in conjunction with Loctite 7649 activator works extremely well. All of the quarterlight window catches in my Dinos are mounted using that and only one has fallen off in the last 6 years. A bit of cleaning and then re-fitting using these products has seen it stay firmly in place for the past 2.5 years. Mounting the catch using a small shim has also helped reduce the pressure on them.

    Thanks all. Got some Locktite epoxy. Now, I just have to wait for the Colorado snow to let up and the temp to get a little warmer before I apply. Thanks again for all of your help. Have a great holiday season.

    I reduced the sealing pressure by hot knife trimming the black plastic striker.
    :)
    When you close the latch there is too much rise to the jamb point leading to breaking forces. Reduce those forces, trim the back side of the black plastic jamb to retain visible profile. A little tricky as it is double rivetted in blind.
    This is best done as the frame is out of the car

    The new adhesives are far better than 1960's technology but that focus seems rather narrow.
    The systematic problem is that there is too much pressure at the latch (my adhesive held, the glass broke a dish shaped chunk off, see photo). Focusing on adhesives is the brute force solution but can we reduce the pressure overall to mitigate the use of super adhesives?

    Found a better way to reduce sealing pressure with a side bonus of access to fully clean the chrome; remove the black striker pad and grind the back down so sealing is at a lower height.
    Use a pick, remove the cover then drill out the rivets. Grind down the back side to reduce sealing pressure on the latch, rivet back in and insert cover.

    I also took the chance to add an angle to the take up ramp, polish the black plastic and clean the chrome underneath the pad

    Scott, what an elegant solution! It looks completely original, yet solve the issue of too much pressure on the window latch/glass. I too have re-glued the latch to the glass, only to have the pressure on the latch pop a dished sliver of glass off of the wing window. I never thought of thinning the backside of the striker pad to reduce the force. Great idea!

    How did you grind the back side of the plastic piece?
