Chevy's of the 40's because I live in the same town. I think though that factory OEM were angled such that it was steeper by a couple of degrees. I made my own from Aluminum but the broke at the threaded screw holes. I went with the steel ones and they worked fine. Not sure if the window leaks yet as its is not on the road. I greased it up inside where the "V" inserts into the frame. I also sealed my windows with urethane window sealant. Used Steele rubber on the outside rim. Used a non hardening sealant in that grove.
