For some reason Detroit lockers are hard to find around here.I spent most of the day hunting one for my 90 V6 4Runner.They all wanted me to buy a 4 cyl unit and use conversion bearings.I said BS!If this is common knowledge then I'm sorry.But if you want a V6 Detoit soft locker for your vehicle call ringpinion.com and ask for PN 187S61B.That way you can use your stock large bearings.
