I used the ring and pinion for a 87 Conquest Tsi/Starion. From what I could find back then the rear axle used in the Tsi/Starion was the same axle used in the Raider/Montero even with the LSD. Was really difficult back in the early 90's to find any parts or mods for the Raider. Thank God for the internet. Makes the search alot eaiser today. Had to even make my own body lift for it. I was able to lift the body the 2 inches needed for around 30 dollars. Will do a seperate post on what I used to do the lift incase others are interested in a strong/cheap lift option.
