I have a stainless ball with a 1" shank. It is very hard to get the coupler latch down on it, due to the ball's "stem" being larger than my other ball, a chrome ball with a 3.4" shank. I do not want to use the 3/4" ball in a ball mount with a 1" hole.
How do I adjust the internal part of the latch to "loosen" it up a tad? I don't see a bolt on it.
