What size mast stepping pins should I get for a Com-Pac 23/IV?
You mean the pivot bolt? Got a bump from the facebook page. It is a machine bolt with a wing nut. The one on my boat is somewhat longer because I used a boomkicker bail and rolling shackle to install my vang. I still have the old one somewhere, will measure when i next go to the boat. Maybe someone knows. pic below.

also this will show the wing nut side and the use of spacers to fill the gap between the step and the mast. You can get the nylon spacers at any hardware store'
