Mexican Spec 1966 Valiant Convertible 4 Speed

I saw a '77/'78? what they called a Volare Superbee in Mexico in late 90s. It had a higher compression and performance 360 4-speed that easily out performed anything around it. I noticed that car had is neither Plymouth or Dodge factory badging. I asked. "Is this a Dodge or Plymouth?" The answer I got was "Si"
