I don't know what seats will fit your Ranger but what I have found out the hard way is this.
I attempted to put seats from a 1994 Ex into 1998 Ranger and it was a no go.
Although the mount had the right bolt pattern the size of the bolts changed, the seat belt setups were different and the wiring connectors for the seat controls were different too.
Although all can be overcome what appeared to be a direct swap wasn't.
Double-check what will fit what at the nearest Salvage Yard that will help you.
Luck,
