You can price check used seats from wrecking yards on car-part.com
In my area(Nor-Cal/east bay) I'm looking at around $500 to replace both sides of my 60/40 cloth setup. I don't have my money together right now so I'll shop it better when I am. I was searching on 99 Ranger. But from the info from this forum their may be better direct fit models to shop on.
