I was driving home from work last Friday and saw a 1959 Ford Galaxie hardtop. Yesterday I saw an all original 1956 Chevy Bel Air convertible. Pretty cool. I have never seen these cars in my area before.
I usually use white glue. I let it get tacky before laying the glass in the body. The good thing about white glue is that any excess that gets on the glass can be wiped off immediately with a water soaked paper towel.
