CA350 replacement, coupling for expando van

A quick TEMPORARY replacement part for a common failure piece on the expando van. The CA 350 coupling wasn't originally designed for this piece of equipment and is prone to failure, but is difficult to source for replacement. This part, in theory, is designed with the intended application more in mind. It is still in a rough draft form, but should hopefully be functional. Will test and update soon. Still need to attach to the metal bushings with threaded holes with an adhesive.
