It may be that none of the FX4 shifters are a direct bolt on.
In the late 90s, Ford changed the orientation of the flat on the transmission shift stub 90 degrees. So it possible that the 97 MAY be the earlier type (wedge bolt sits front to rear). All FX4's have the later style (wedge bolt sits crosswise). This is something that you definitely need to check out before taking out a 2nd mortgage to get an FX4 shifter. A quick look under the boot will tell you.
Late style standard Ranger and FX4 chrome shifters (these are a direct swap with each other):
Earlier style shifter with fore/aft bolt (FX4 shifter will not bolt on correctly)
