I have a 2.73 posi carrier and ring gear from a 1965 Dynamic 88 that I would be willing to sell for $200 plus shipping. If your car is already a 2.73, 2.93 or 3.08 ratio open rear, you can just swap your ring gear onto the carrier. If you have a 3.23 or higher open rear, I believe you can use a 12 bolt chevy Mr. Gasket ring gear spacer and still swap your ring gear onto it (though I have no experience with this and thus cannot say for certain). It would be ideal for someone with a 2.73-3.08 open rear who wanted to convert their car to posi-traction. I'll throw in the correct paper gasket (Victor Reinz part I mentioned earlier in this thread).

Should work for all 65-67 big cars, excluding Jetstar 88s.
