1965 Dart or Valiant Early A Body 7-1/4 Sure Grip Differential

7 1/4 rears do not use “green” bearings. The originals are not adjustable and only last for 100K. Just replace the axle bearings and seals, pull the back cover, replace the gasket or seal it with RTV. Fill with new differential lube, Dino is fine, for limited slip and enjoy.
