Like the title says, I am looking for a 2006 or 2007 Getrag Differential with posi and either 3.23 or 3.42 gearing to work with the V8 Roadster rear end kit that I already have on order.

 

I purchased mine from the local LKQ. had ~60k miles, G80, with an 8 month warranty for about $170. Just an FYI.

 

Thanks a bunch for the solid.
I called LKQonline and they were able to cross shop for the differential. According to them the 2006 & 2007 CTS-V was only available with 3.73 gears but some other Cadillac models use the same differential with 3.23 gearing.
Mine is $350 delivered
No warranty because I am doing a swap.
Took me longer to type this message than to order the differential.
