There are some minor changes over the years, but the body mounts never changed.
Some of the frame difference I can think of, track bar bracket in 76, gas tank mounting in 77, rear shock mounts in 66. Then there is the difference in I6 to V8 engine perchs. Bracket for the charcoal canister is minor enough I don't count it.
Steering mounting, suspension mounting (minus the track bar), body mounting, transfer case mounting all stayed the same.
