easy,easy,easy to do on the pre'65 models, four nuts drop the backend of the driveshaft, 10 lug nuts, eight axle retainer bolts, jerk both axles out about six inches, the remove about 10 center section bolts, get a pan for the 90 wt. pull the center section out (its heavy) then stick in the next one and reverse repeat(dont forget the oil)--change out to the correct plastic speedo gear in the transmission's tailhousing to keep the speedo working right, and enjoy--dem Camaro and other salisbury rear end boys just wish theirs was so easy. If you get good at it, it could be a 30-45 minute exercise.
