70 Swinger 340

Yes, the button is rectangular and has a stem that pushes on the latch mechanism inside the upper seat frame. its a pretty stout latch that just needs a little lube when you pull it apart. very easy! not sure if the seats are exactly the same, When ordering the parts from legendary, they said they didn't carry new foam for the 70 A body seats, they do show replacement foam for the B bodies. I guess I cant imagine that the 70 A and B seats would be that much different. I guess im saying im not sure if your seats are the same!
