No problem Jeff, Cajun Bandit and the Ribolator site both sell them along with the ring. I have 2 Weber spits I got from Home Depot for cheap on clearence, the only thing I had to do to make the Weber work is trim my Cajun Bandit tabs that hold the motor to get it to fit. The Weber is slightly smaller and I have to turn it upsidedown to get the spit rod to line up.
The motor from CB and Ribolator are made to fit the ring and are wireless also, something to think about.
