Help: 75 Scamp Seats in 74 Valiant?

They should, I put 74 Valiant brougham or Dart Special edition seats in a 70 Dart, the only difference I found was the hooks for the seat bottom were in a different spot. The top section or backrest may have the tabs in a different place as well, but they ony have 1 bolt on each side, easy enough to drill a new hole if needed.
