Nope, you cant even convert it to an alltrac sedan (yes they exist).
Well you can, but it will require extensive modification. The floorboard of the car is different in the 2WD and 4WD versions. As is the rear axle assembly.
Well that anwsers my question about the potential "AllTrac" 1997 Sedan. I woulda thought that the floorpans woulda been at least similar. I was looking at a scrapped wagon last week and I realized that was totally different, but I had had high hopes for the AllTrac sedan (since theres one of those there too).
