First off....those snowflake wheels are super rare. Great score.
Secondly....there's only one source of parts for those in the world.
I'm not making this up.
Google Indian moped parts and you'll hopefully find the guy who bought THE ENTIRE INDIAN MOPED LINE back in 1983. He's got pretty much everything you could want....not joking. MY buddy got some stuff that he thought would never exist, but this guy has it. All NOS stuff. He literally bought a container of parts from the bankrupt company.
Google it. It's your only option other than selling than thing.
