J/105 Trailer Question

[Monkey]

I’ve got the easiest question ever. Anyone know what size hitch ball I’d need for the standard Triad non-gooseneck trailer?  

 

[SEC16518]

It should be 2-5/16

Thanks!  Very much appreciated. I didn’t want to drive 3 hours to pick it up only to get sidelined by a hitch ball that’s hard to find.
