Help needed with setup/Rigging with Constraints

I have a scene with a number of Hydraulic Cylinders on angles, I’m having problem keeping the Rams in line with the Cylinder Barrels. I have tried using the Slider Constraints but they only work on the axis (90 degrees), I need then to be easily changeable because they’re in different positions with the animation/scene.

Thanks,

    For this example, I will refer to a base and an arm, and the barrel and ram are interchangeable to meet your needs.
    * Parent the arm to the base with a rotation constraint (Move hotspot to the pivot point.)
    * Parent the barrel to the base with a rotation constraint (Move hotspot to the pivot point.)
    * Parent the piston to the arm with a rotation constraint (Move hotspot to the pivot point.)
    * Add the Point At modifier to the barrel, set the target to the ram and adjust the axis options as needed.

    Isn't that just a Shaft constraint? Parent the ram to the barrel, apply a shaft constraint to the ram's motion, and you should have it.

    I think....
