Hyd info: Originally these cars had brake fluid for the hyd top system. Usually leaves a mess when they are out of use for a length of time. The pump is very simple and is powered by a motor most old Starter/gen/alt shops would have parts for. If your system is brake fluid, it can be purged and replaced with ATO. The one piece that is hard to come by is the switch so be careful with it. Replacement cyl are available and I had hoses made up at a local hyd shop. There is some excellent information in the Ford Svc Bulletins on the system. I would recommend getting a copy of the Post, reproduction Ford Service Bulletins 1941-48.
