I have enough "stuff" to build two more big bores and I know somewhere in the "storage" I got a set of bare cases from a man who said they were off a 5 speed, but he had a complete cluster, drum and forks to turn it into a six speed. I got them because it came with a cylinder I wanted and the cylinder was cheap for a cylinder. Anyway, see what number you have to have and I may have it sitting idle one way or the other. I can ship and I keep saying I am coming down this winter.
