Need HS40 Crankshaft

[Phosguy]

I am restoring a 1970 Rupp Roadster with the HS40 engine. Of course, the engine was shot as well as the crankshaft was not correct. I found another HS40 - 55388C so must be a newer engine but this crank is not very good. What item number should the crankshaft be for this HS40-55388C so I can reference looking for one? Any recommendations on sources to find a crankshaft?
Thank you and Happy Easter to all!

#33080 is the only crankshaft used in the HS40's that rupp outfitted their bikes with regardless of year made. It is a the only Ball bearing supported, long PTO crank that Tecumseh made with that flywheel taper.
