I have a set of 4.11 gears (I think)...
They came with a Posi carrier that I bought on Ebay.
8.5 inch corporate ring gear.
I am hoping that someone has something closer to 3.43 gears... I might even take a 3.73...
If you want to trade straight across, just let me know.
Thanks,

 

Get ahold of Brian Trick (507olds on ROP) He will have what you need and might do some swaping with you

 

I would gladly contact him.... although I don't know what "ROP" is.
I am relatively new to the oldsmobile forums, so I am unfamiliar with the acronyms.

 

Sorry ROP = Real Olds power
I was very happy with the deal i got on my new Eaton Posi from him

Trick is a good guy and very easy to deal with. I have one of his rears in my F85 and have gotten lots of parts from him. JKaz
