Measure the outer diameter of the cylinder, then measure the length between pin holes (with the center rod pushed all the way in to the cylinder) to get the approximate push/pull length, then measure the diameter of the push/pull rod. If you have a pin in the attachment points, measure the diameter of the pin (usually 3/4 inch or 1 inch diameter).This will give you a reading of something like a cylinder (3 inches inside) for 3 1/4 inches outside, type of attachment points, size of pins, and over

Order mainly by length, not bore and stroke, then get the rod size as close as
