Not sure of the years but Ranger didn't change much in the rear.
I have a '95 bed on my '03 chassis, the bumper came from a MA Ranger Owner, not sure of the year of the bumper, sorry.
You need a Steppie or Flair side Bumper, the style side will not fit, wrong cut outs, width might work.
Only problem, most of the OEM Bumpers on Steppies have rotted out before ever making it to the JY.
If you are interested in an aftermarket Rear Steppie Bumper, check out my rear bumper, made by Custom 4x4 Fabrication, in OK. Mike, the owner, does GREAT work and has a design for a rear Step side bumper.
