Hitch balls are available with shank lengths that are short (less than 2 inches), medium (between 2 and 3 inches) and long (greater than 3 inches). The drawbar thickness determines what shank length is needed. At least one thread needs to be visible beneath the lock washer and nut once the ball is screwed into place.
When choosing a hitch ball you want to make sure you match the ball shank diameter hole in the ball mount. One of our most popular hitch balls is part # A-90. This has a 2 inch diameter ball and a medium shank. The shank measures 1-1/4 inch diameter and 2-5/8 inches long. This is designed for a drawbar that is 1/2 to 1 inches thick. For the drawbar you said is 3/4 inches thick I recommend choosing a hitch ball that has a medium shank.
