Ok, So I have broken my 12 bolt twice with a 6 speed. It is out of the car right now headed for rebuild. I will not sell it to anyone with a 6 speed car! .
It would be great for your A4. It would be complete 4 channel with 30 spline axles, Eaton Posi with steel clutches, The girdle cover, Backing Plates and Reluctor rings. I have not gotten the gears yet I will put 4.10's back in but if you want to buy it. I will have them install whatever you want.
I am looking to get 1800 firm as Shipped to your door. The rearend is about 6 months old.
The rebuild will be done by Dan at Northwest Differential in Kirkland.

 

sent you a pm

 

Would you by chance be willing to sell just the housing. If so how much. BTW where is B-Town

 

How much power are you making that you break the 12 bolt? And what parts exactly broke and how many miles were on it?

 

How much as is? I'm local, not really looking for something right now but if I could get the housing for a good deal I'd have to consider it

I'd probably want to go 3:73's if I'm going to stick with the auto....
