Carb to engine boots are also unobtainium. That will be an issue on most of them if you don't want to use radiator hose and worm gear hose clamps....yuck. Anyway, I have one I am chopping into a King Rigid this Winter if I get it running. They are like riding a moped and I get board wanting to shift and clutch. The jockey shift install is sure a no brainer.
