These parts I have named are the actual lifting mechanism or 3 point lift. Where I name the Lift bar, that is the attachment point for the rear most part of the lift bar, I didn't have mine on at the time of these pics. Once you have these parts you can then attach the Sleeve Hitch adapter, which are the items you have listed in your link. You will also probably need to buy Frankenstein bolts to mount the rockshaft to your frame. Jeff in PA, a member here, makes some very nice ones for a great price. I hope this helps. A pic of the back of your Cub will help determine if you need the Frankenstein bolts or if you just need a 1/2" rod to run thru the rockshaft.
All Parts mounted to enable use of Sleeve hitch mountable implements.
