Hey I have a complete posi trak differential from a 88 bronco ii. It is complete with a 3.73 ring gear and pinion plus bearings and spider gears. I ran it in a 98 ranger for 3 months but I pulled it out and went back to the open differential. The unit is in perfect working condition. I am willing to sell it to you for a low price, just make an offer. I am located in Boone NC. Call me at 864-979-0333 if your interested
