Differential by DANA Corporation
Sometime in 2005 the rear end was changed to a Dana Corporation IRS unit.
This is the same unit as used in the Superformance Coupe.
I believe it was produced only Australia maybe by "BTR".
The 3.46 ratio is standard.
Other ratios that were available were 3.07, 3.46, 3.73 and 3.91.
Perhaps the part number for this differential is #0180-000007.
The same rear end was used on the Pontiac GTO in 2004 & 2005
Allen bolt sizes for the half shafts reference to a 2005 GTO
The GM part number might be #92180093.
They are probably metric M10X1.25X50.
I have an exploded drawing of it somewhere.
