Thanks, all. I debated about tackling these one piece windows, this is new territory for me. It's a Hagan kit and the instructions look pretty good so we're going to give it the old college try.

As far as the handles, there's serveral different styles of reproduction handles on Ebay that lock. I havent picked a specific one yet but the late 30's Ford ones look pretty good. I just have to figure out how to make the handle fit the Plymouth trim plate that it mounts to. What kind of locking system did you end up going with?
