Borg Warner Rear Axle

Need help identifying rear axle. It is stamped Borg Warner and has disc brakes that are mounted opposite of one another. It also has a 3.70 or 3.73 gear ratio. I was told 87, but thinking it could be an 85 or 86? Any suggestions one what I may have?

Re: Borg Warner Rear Axle

Pre 1989 BW 9-bolt rear with the Iron calipers & 10.5 rotors, 1989 had the PBR calipers & 11.655 dia rotors. Your guess should be correct for the year.
