Update: Ingeniously, I swapped the top section off of...get this.... a Taiwanese Peugeot kid's bike. And I think it'll work. So I must have an 80's moto. The Tange fork, BTW is a Tange 3C, if that helps anyone out there.
I need to get calipers to measure stuff. Right now it's all trial and error and intuition.
Hey thanks to all for the help. have a safe and happy holidays!!!!
