Hello all...well, I replaced the motor for the convertible top in my 1973 Cougar convertible, and it worked - for about ten minutes. And in the interest of full disclosure, I didn't change the motor, a local shop did, and they did NOT tell me that the cylinders looked bad. But they must be, because the new motor is trying, but the top will not come up. So I just ordered new cylinders and hoses from West Coast Classic Cougar, but I forgot to ask them on the phone how to bleed the lines once everything is installed. I am going to try this myself. I'm comfortable tinkering, it's just that I've never done this before. I've read in a couple of places about vacuum pumps, etc., but I'd love to hear from someone as to A) how difficult it really is, and B) what their experience has been as to the easiest way to go about it. Thanks again for your help, Tyson.
