I don't know about the 1996 models, but I've looked into aftermarket seats for my 2002, and the biggest problem isn't the seats, but the seat belts. The 2002 has the seatbelt integrated into the factory seat, and, as a result, there aren't too many options aside from installing a full cab roll cage, or losing the back seat seating capacities.
When I was looking at seats, I was looking at the following:
Beard
Corbeau
Recaro
Sparco
Good luck
