340 torque converter...

340 torque converter is recommended a lot here to a lot of people. Does anyone make these "off the shelf" ? And yes, off the shelf should be available since it's a replacement part. Not one that "will work" in it's place, or "should be about the same"... but one that functions like the original because it's designed to be the replacement. I shouldn't have to call PTC or Dynamics or Coan to get a replacement for a factory converter.

Thanks,

I cant get original parts from the original manufacturer for a 2019 let alone a 50 year old engine. Brave new world out there.
