You are all mixed on on most of what you have been stating in this entire thread.
There was no Bel. or Sat. in 1964. The Sport Fury was NOT replace but was turned into a C body when they began production in 65 and continued to be available through at least 71.
Sats and Bels were basically family cars through 71 as they were offered in 4 doors and additionally many people bought 2 door family cars as well. You can consider the RR and GTX as "sports" models but MOST people refer to them as muscle cars. The only TRUE sports model based on what Chrysler built it for, referred to it as, and marketed it as, was the Charger through 1970.
1971 changed everthing when they combined the Dodge B Body line of 2 door as Chargers, Charger SE, Charger Super Bee, and the R/T. Plymouth did it a little differently dropping the Bel but continuing the Sat in a 4 door and adding the Sebring in both a 4 door and 2 doors with various models as well as the RR & GTX in the basic Sebring platform.
Yes, starting in 71 The Sebring high end 2 door models became competing models for the other brand "luxury sport" models like the Monte Carlo etc. However the pre 71 Plymouths NEVER had anything that was considered a competitor for the luxury sports cars listed above and in previous posts INCUDING the Sport Sat. The Sport Sat was simply a competitor for cars like the Coronet 500, Chevy SS Chevelles, Ford Fairlane GT, etc.
