I don't think there is any difference in the body but I am no expert. It could have had a complete frame change. Someone could have changed the door tag and glove box door from another truck.

All the 2WD Suburban's I've seen have had coil spring rear suspensions. I have seen 4WD conversions that left the coils/trailing bars in the rear. All 4WD would be leaf sprung in the rear.

It has been said, a partial VIN is stamped in the drivers frame rail. I'll take a look at my 4x4 and see if I can locate it.
