Can someone tell me what glue to use to attach these latches to the glass?

That is a mystery that has been debated on this forum probably forever.... So if you do a search here you will find a lot of good suggestions on various adhesives and prep methods that seem to work. After you get them re-attached, one trick is to basically just never latch them unless you need to, as in a rain storm or during car washing something like that.

J B coldweld the liquid stuff just use a bit

I am planning to take my car to a local auto window shop and have them install them. It is my understanding they media blast the glass and latches and then glue them in place.

theres also a acid "sold in stainglass shops"
that etches the glass

I tried all the glass adhesives in the parts store with no luck.J B Weld did the trick!!!

my vent windows do not have any latches can someone post a photo of what they look like?

Thanks for the tips. If I find anything over here in NZ that works I'll let you know
