I have some good hard to find item here.

1 2 series 12 bolt 'O' type posi unit 31 spline unit for FULL SIZE Oldsmobile cars

1966-1970 Delta 88, delmont 88, 98 olds, wagon, 88 royale ??/ Not sure exactly the name of the cars that were in that era.

I also have the 31 spline bolt in axles also with good bearings and reatainer plates they are 31" long each

I have a nice set of 2.73 gears also.

I have the housing also but all the perches were removed for it...if that is something you think you would want or could used it is here 30.00 + shipping.



299.00 for the posi unit
99.00 for the pair of axle shafts
50.00 for the 2.73 gears
Again this stuff is pretty hard to find so if you what to stock pile some extra stuff this is the time. Jim

Oh and you can install a spacer to use the better gears with this posi unit. Jim

 

I am curious one do you still have this and two would this twelve bolt posi unit replace and fit in the rearend I have in the car now.I was told my car has a ten bolt now
