It is Canadian built 1946 Pontiac torpedo all original even the paint. It is the 239 flathead six. I bought it with the distributer removed from the block but was in the trunk. It had new point set installed so I am assum8ng it was pulled out to install the points. I slid the distributer into the block fully seated but can turn the shaft by hand with only the resistance of the point follower. Obviously somthing is missing. I'm not finding much info on the drive assembly but one article made reference to a spring clip. I'm hoping to find someone that may have a schematic that I can identify what is missing. Thank you.
