Looking for a crankshaft for my 1970 Tecumseh HS40

#1
All, still looking for a good crankshaft for my 1970 Rupp Roaster with a HS40 Tecumseh motor. Want to keep it nostalgic. Can anyone provide me with direction?
Thank you

The crankshaft for that engine was specific to Rupp as the PTO end was longer at 3". It will be a challenge to find and it will be $$$$ (Been there, done that!)

Those cranks were made from Arma Steel too... They're pretty hard to find, but if you're not using the original driver, you can use a shorter crankshaft (standard 2-1/4")
