Guys, First post here so bear with me. I received my 32" BB in late summer and had so much fun just grilling that I'm just getting around to getting the roti set up. When I finally opened it up I noticed that I clearly need the square/hex roti shaft to go from my motor to the hex nut on the outside (it doesn't appear that the hex nut goes all the way from outside to inside) but then I also need a hex/thread drive shaft to get to the cradle itself to actually turn it. The photo shows everything that came with my "16 kit" (with the exception of the "L key"). Clearly, I'm missing some pieces. It looks like I only have the rotating shaft at the end but no way to actually drive the cradle! Any help (and overnight shipments of parts so I can do a rotisserie turkey for a work outing by the weekend...) would be greatly appreciated.
