Figured I'd let you guys know my outcome.
I pulled my bench out to see what holes I had and how everything was set up. Sure enough. All eight holes were pre-drilled in my 97. The four extra holes were not tapped, but I simply ran one of the seat bolts down into the hole and it threaded it EASILY. Those seat bolts are tough as nails. I used one bolt to do all 4 holes and it has ZERO damage to it.
I found a 2001 Ranger at a local junk yard. It had the vinyl 60/40 seats that were in darn good shape. They fit fine, though they sit a little higher than the stock bench I had. About 2". I think it's going to be OK, but it's borderline. Any more and I don't think I'd be able to deal with it. But it's fine. Just gonna take some getting used to. Also, the 01 vinyl seats had the seatbelt clips built in. The seatbelt buckles in my 97 would not fit into them. So I had to remove the seatbelts from the 01 as well. Of course.... both the seats and the seatbelts were all held in place with huge T55 torx bolts that hadn't been budged in 13 years. A real PITA trip to the junk yard. But everything is installed and working in my 97. No real modifications needed.
