Wanted 1950 Buick Window In-Door Hardware

Hey everybody. I'm in need of the in-door window mechanicals for a 1950 Buick Special Tourback Sedan. I have/can get glass, but need to find the regulators, sash channel, and any other tracks. I'll be buying new felts/rubber components. I need the hard goods. I found that components from a 1950 Super or Roadmaster should work as well as 1950-1953 Wagons.
