File, image Most important in this case are the dimensios of the cylinder, and specially those related to other parts like the link. See the context of where the cylinder is used. image image

The cylinder I put in the cad is there just in order to calculate the geometries of closed/ open position. Different brands of cylinder are not important. Not even different types. The one in the drawing is a tie-rod cylinder, but a welded cylinder could be used as well. As such the above is 2" dia meter cylinder, but I propose that a 2.5" diameter cylinder should be used.

To make things easier about the cylinder. Its specs are: Cylinder retracted length from center to center of pins: 16.25" Cylinder extended: 22.25"

They are common 2"(bore dia) x 6"(stroke length) dimension cylinders, like these
