    The glass shop is having a problem with this...
    Does anyone know what gasket will fit inside the groove of the inner frame to hold the glass in place??

    thanks

    The item I linked above is the inner-to-outer frame gasket. The glass gasket, surely, is a simple u-channel? JC whitney used to list all kinds of those, shouldn't be difficult.

    My glass guy looked at mine and said he would just silicone it in place. But if you do fine the right stuff, post up because I need some as well.

    Apparently it isn't as easy as it would sound. The glass shop cracked the first glass...

    They were using some sort of rubber -- "tough stuff" or something like that and it was too thick.

    The gasket needs to go into the channel around the glass. The glass is almost as thick as the channel, so the gasket needs to be very thin. Once that thin it lends itself to tearing.

    I'm sure someone here has loaded glass into a vent frame and I'm just looking for a little insight and hopefull for a source and name for the gasket that'll work. I've got two vent frames to do, so they are saving the pattern for the next 'go round.

    The glass shop will probably find something, I just thought I'd do something on my end if possible

    I would suggest a black mastic if it comes to that.

    Are they using the correct thickness of glass, ya think?

    I am sure he has some professional stuff. They do a lot of automotive work. But he said it would not be a problem. Especially once he saw how the inner frame came together.

    I seem to recall reading that prior to the early 50's/late 40's safety glass used on vehicles was thinner, can't find a reference to it now though :(

    edit- did find this though-

    "Jim Thode Chehalis Washington [/URL][/B] on Friday, July 26, 2013 - 01:40 pmHere is what was wrote in a previous thread:
    "Laminated safety glass comes rated AS1 and AS2

    AS1 is slightly thicker and is the only thing legal for windshields.

    AS2 is legal for side and rear windows.

    Some early antique car windshields have very narrow grooves and will not accept the thicker legal AS1. The trick is to have the glass cut so it leaves the AS2 off of the finished piece. Glass shops will not and can not legally install AS2 in a windshield but they will cut it for you to your pattern as I have detailed here. Just do not tell them that it is for a windshield. Then you take it home and install it. We wrote the safety rules for mandatory safety glass in anitque cars in the 1960's, but we carefully only stated safety glass and not AS1
    . "

    It seems that on my windshield, there is a sort of white glue.
    I plan to change one glass and I wonder how to do.
    By the way, do you have these glasses in US? Easily? You make them cut at the model?

    I don't know if my inner glass seal for my venting w/s is original or not but mine almost looks like its basically similar to a bicycle tire tube and guessing around the thickness of a SD memory card for your computer. just a flat piece of rubber strip that was used. my glass will be replaced here shortly since it is cracked on one side and all the way round it has weird bubbles around the edges im guessing water got in there and froze?

    I just read through both my parts books for 3b 5 and 6 and don't quote me on this but I am nearly positive my book is calling it "Strip, windshield glass (69" long) part number for cj5 is 956310 and quantity of 2.

    Like I said before I have not yet removed my windshield glass so I don't know if its in 2 pieces or not but this may be a start or something to research futher.

    The bubbles are caused by the delamination of the safety glass. Safety glass is used on all automobiles and has two layers of glass with plastic in the middle, so that if the windshield were impacted, it will hold together and not shatter in your face. this is why it is important to always make sure that when you have a piece cut, don't just have your local hardware store use regular glass, make sure it is auto safety glass.
