I have a 1963 Plymouth Sport Fury Convertible. I am at the point of reinstalling my power top system. (hydraulic hoses, top cylinders, and pump.) I want to flush or (clean) the hoses, cylinders, and pump reservoir. What kind of solution can I use without damaging anything. Also, should I use automatic transmission oil or hydraulic fluid. And last but not least, what is the procedure to charge the system. This information would be so helpful. Thanks, Tom.
