Hey All,

I'm wondering if anyone has a 10 bolt or a 12 bolt posi rear end for sale, fully assembled and ready to go. It's gotta be 28 spline and I know it's asking a lot, but if it has a higher number gear in it (3.55, 3.73, 4.10 etc) that would be perfect.

If not, does anyone have a posi carrier for sale? I'm not looking for one that's got a lot of miles on it or has been highly abused, the more details about it, the better. Again, if possible, 28 spline.

Thanks everybody!

It would help if you said what rear you have so folks will know if they have a carrier for you. Do you have an 8.5" 10 bolt, 8.2" 10 bolt, O-Type 12 bolt, or Chevy 12 bolt?

If interested I have a super clean low mileage 12 bolt factory TW code 4.33 from a 68 W30 but I think it's a 31 spline axle. Not 100% sure on that though.PM if interested. I'm located on Long Island.

Original poster did not even state what year and model car for.

More information needed.
