Cabriolet glass runs?

[theHIGHLANDER]

Is the glass framed for a cabriolet? It's hard to see in pics because they always seem to be windows or top down. If so, where can someone get a metal glass channel for the 1/2" glass frame to slide in? Everything I find, and I mean EVERYTHING, is a max of 7/16, and glass frames I need to channel are a full 1/2. What are some of you using, but more important, where do you get it? Thanks in advance.
