well after some research here is what i found... i wanted to go towards the more modern rubber trim because i have a leak that hopefully is fixed now in the passenger top corner.
but with trying to service the leak, the trim obvously got alittle bent and i just dont like the metal trim and then while putting it back on the outmost "stud" broke off... but i think it'll be ok for now.
i do have a few chips in my windshield so my wife was wanting me to get it replaced anyways... so thats when i started to venture into the idea for my trim...
so what i found is this stuff you can google if you want... flexitrim... i found a whole 5 page discussion about replacing the metal trim with the newer rubber trim on a 4 Runner forum the other night and thats when i really found head way...
basically the windshield has the flexitrim install on it prior to installation on the vehicle and then the windshield is installed.
so basically the flexitrim just bridges the gap between the raised part of the body and the windshield... the same thing that the metal pieces do.
heres the thread for the toyota

and if you take the time to read it, i believe page 5 someone says that safelite actually carries this stuff also... so im gonna make a call to them today and inquire about it. the only issue that the person that used safelite had was that the bottom cowl piece was too narrow, so he purchased a wider piece
