    Terrible info and YouTube vids online for this for 84-88’s

    There are two different windshields
    Bigger for glue in applications
    Smaller for rubber weatherstrip / gasket / seal

    84-88 and 1st gen 4Runner - gasket seal part number - 56121-89117

    Searching domestic (U.S) auto glass vendors, there is only one size windshield available for glue in apps for 84-88 that is too big to run the rubber seal / gasket

    My solution - I trimmed the cabs sheet metal lip , about 1/8th inch each side , maybe 1/8th to 3/16th top and bottom and got a great fit using the standard US “big” windshield

    if you’re going to do this, take your time, better to trim too little and then have to trim a little more than to remove too much and have to add material back

    Supposedly you can also trim the windshield glass to the smaller size but being a metal fab dood , trimming the metal cab lip was something I felt more comfortable trying

    89-95 info - gasket seal part number - 56121-89121
    Or browser search LN85 windshield seal rubber or something like that

    You CAN buy the smaller windshield for 89-95 in the US needed to run the rubber seal

    Why would you do this - easy pulling/installing windshield for racing or race car prep , cab repair, roll cage access …
    Because rust and the plastic trim glue style is ugly

    Why would you not, because supposedly it makes the cab structure weaker if the windshield is not glued in

    My 1987 below where I trimmed the cab lip and used the bigger US windshield for glue-in apps

    My 1989 below where I ordered the correct and US available smaller windshield for rubber gasket seal apps

    I'd love to install this - your truck looks great! My trim is shot, and I costed out trim and clips at ~ $450!

    I don't know the details on the 56121-89117 gasket - is there a slot for the body flange, as in old-type weatherstripping? I'm a metal guy too, so the trim is not a problem, but I like to have a picture of the outcome in my head before I start! Thanks!
