Rear Axle and Suspension Assembly from a 2004 Pontiac GTO that had an automatic transmission. Axle has 60,000 miles on it. Includes everything as shown in pictures.
$350
This should also fit the 2005 and 2006 models but I will leave that to you to verify.
I would prefer local pickup (Springfield, OH, 45502), I am guessing shipping by truck would be around $200.
