I can't remember either. I've had multiple trucks from each of those three generations and I can't for the life of me remember what the seatbelts were like in the earlier or later models. I also remember some with the reel up high, but I'm pretty sure that's the 79 and earlier. The cabs were all the same from 80-96, so it seems like all the seatbelts would bolt in with the only difference being appearance and some would have contacts to activate a seatbelt light. It doesn't help that mine has the wonderful whorehouse red interior that Ford loved so much back in the day. I've been trying to find picks on the internet, but so far no luck. A friend of mine has a Ford truck grave yard. I may go visit him this weekend and do some looking.
