You may not be able to see this yet, being a newbe. Contact Stewart and tell him you need a KIPPS bolt. Lose the ball bearing idea forever.

Age old trick. Works well but too many parts to keep track of. And, you will never find the right size ball anyway.

search option up top, search for "bolt-mod" and you will know what you're buddy is talking about too.
