Get a Quick Hitch and keep your turnbuckles. You will never get the telescopic arms to align where you want them. The holes rarely align where you need them, so they'll be too loose, too tight or the arms offset to one side (hard on equipment).
A quick hitch will make you convert all your implements to a single Category. Don't ask how I know. But it's worth the effort if you have more than one implement. It might also make you buy a hydraulic top link to save even more time.
