The K1 was/is pretty limited as a pax/cargo aircraft, as it doesn't have the main deck freight door and pallet-compatable main deck of the KC1's. IIRC the K1 could carry around 200 pax (in the mid and rear cabins) and their bags/mail/small freight (in tins that are small enough to fit through a pax door) in the forward cabin, and that was it.
I always thought the ex-Pan Am's were deliberately kept as pretty much conventional TriStar 500's, in order for the 3 of them to primarily service the Falklands Airbridge with a "normal" pax cabin and the belly holds.
