Might sound odd but try Stapleford Flight Centre stores for a crankshaft, they are a Cessna spares dealer and I sourced a crankshaft for one of our Cessnas from Cessna and even though it was a genuine Lycoming part, buying through Cessna knocked off over a grand.
This one might be a possibility for parts etc, though it has had a prop strike so would need stripping and inspecting, you would need to check how bad the strike was before you considered it and if the parts would match though.... it could end up as an expensive error.
