2004 Roadtrek 190P Crank Out Window Parts

[SteveD]

My driver's side rear crank-out window became loose. Luckily, I was able to spot it before the glass fell off. The bracket on the left side, where the glass attaches, looks missing. Does anyone know where I can find replacement parts? I may have to rig up something if I can't find any parts.

Thanks for the help.
