2007 Trailblazer LT
My truck was built in October 2006 but sold as a 2007 model. What exhaust manifold do I need? Will the Dorman 674990 fit or do I need something else? Ebay lists manifolds for a whole bunch of years but interchange doesn't list them as a match for my 2007 despite looking the same. Will any years other than 2007 fit? I can get a new manifold for a 2004/05 TB dirt cheap but not sure it will work on my 07...
