The spacers for the engine plate are not required at all. It just keeps the crank flange on the inside of the plate instead of it protruding beyond the back side of it and maybe being a pinch hazard. Most engine stands have tubes welded to the ears of their adjustable arms, so I was just keeping with that tradition in case someone wanted the extra spacing. They are not welded to the plate, so they can be left out if desired. Thanks
