I looked up the Shelby 5133 coupler and it said it uses a 2 inch hitch ball.
You will also need to get the right ball shank diameter and ball shank length. The ball mount will determine the diameter and length. If you measure the hole size diameter in your ball mount, that will give you the ball shank diameter, there is a 3/4 inch, 1 inch and 1-1/4 inches diameter available.
You will need to measure the thickness of the ball mount to determine the ball shank length. Short length is less than 2 inches. Medium length is between 2 inches and 3 inches. Long length is greater than 3 inches.
The Tow Ready 2 Inch Hitch Ball, # 19247, is a popular number that we sell. It has a 1 inch diameter shank and a 2-1/8 inches length.
