I believe I"ve seen (sometime in the distant past) cranks offered for
sale, but I may be mistaken. Are they getting hard to find?

As the A-65 is no longer made, what does this mean for the fleet of
A-65 owners? Do they swap it out for an engine that is still
supported? - Mike



You could likely have a crank custom made for an experimental, but I'm
guessing the cost would be high even by aircraft standards.
