I have personally never seen a 65 Valiant or Barracuda with a factory 8 3/4- been watching since 1965.... maybe they were out there- In '66 I bought a 65 Valiant 100 2 door sedan that had been run full time on drag strip as and F/S car- had 273 Commando - fenderwell headers- and a 4 speed. Had a 7 1/4 sure grip rear- one of reasons they sold car was due to problems with breakage of rear- spider gears and lugs if I remember correctly
