The crankshaft from my 263 is available to the first one who gets here. If you have seen my previous posts, you will know that I replaced the (extreamly leaky) Dynaflow in my '51 Special with a 3 speed manual, and that I found that I had to also replace many other items, including the crankshaft. My Dynaflow-style crankshaft, which was running fine with good oil pressure, has been taking up space in my garage since. If anyone wants it, they are welcome to it. It is in Bismarck ND. (And, I'm guessing, would be very costly to ship.)
