I just pulled the fridge on my 1975 Sovereign
, not easy.
Right hand bulkhead has to come off, bracket under it screwed in, a clue is phillips head screws and not rivets.
Then another bracket at the bottom of this bulkhead..
then the shelf on top has to come off.. a "perhaps" plate to the vent.
Gas line and cord of course. then wiggle it out nice and slow..
