I have a 2007 Chevy Trailblazer 4.2L and I am in need of a high output alternator (200-250amp) I've been looking on the net to buy one and I can't find a single one I've only found a couple available for up to 2005 4.2 trailblazer, but I was told by the dealer it will not fit my 2007. Can anyone point me in the right direction?
