I know that there were many mid 60's models that were factory converted to electric gear before Money made it standard.(a mistake IMHO). Has anyone heard of a plane being converted back to manual gear? I would think that since it was an STC that if you had the parts or could fine them you could simply put the manual gear back in the plane and file a 337 letting the FAA know you removed the electric motors and installed the J-bar i.e returned it to its original configuration.
