I ordered the balls online, these are slightly smaller than regulation size and very comfortable for full sized hands, had a good buddy drill and tap them for me. I hope I did the attachment right with the photo. Orange 5 ball on the tranny and a red 3 ball on the transfer. These are on my old red 89 YJ, a red Islander with the original factory sun graphic on the doors and hood, the numbers are for the gear counts and colors came out perfect. I found this thread hunting for a new knob for my 05 Rubicon and open to any cool ideas, it's a 6 speed but I don't like the number six or the green ball color.
