If you have problems locating the skewers try these guys. For the money they make great skewers. You may have to bend the ends into a hook shape like I did but it's not a big deal.

Based on your posts I decided to check out some local mediterean/middle eastern store and I found some long skewers for $1 each. Decided to marindade some chicken and test them out on the kamado joe. They worked perfectly and as they are so cheap I have no problem bending them for use in my PBC (which arrives tomorrow)
