Here are the convertible top lift cylinders (also called rams), all of our top lift cylinders are completely new and are made as direct replacements for your car. We do not sell 'universal' or rebuilt rams, all of our cylinders are backed with a 5 year warranty when used with automatic transmission fluid. We also have information at the top of the screen with everything you need to know about hydraulic convertible top systems, it is a must read if you are replacing your top cylinders, lines or pump. This cylinder fits 1998-2004 Ford Mustang convertible cars, they are sold individually and are the same for the right or left side of the car. One note--If your car is a 1998 you should check to see if your cylinder is 1 3/4" in diameter or 1 1/4", if yours is the larger size then you should order a cylinder for a 1997 Mustang.
