So I finally splurged and bought the amerihood for the trailblazer, it was on sale for 521.00 and free shipping, came in a large box reasonably packed. I'm very pleased with the fit and quality, very well made for the price, has functional heat extractors on either side of the cowl and the cowl is also plumbed over to the air box if you want to use it in conjunction with an after market air intake although I'm just going to modify the factory airbox to work with it. I'll post pics thruout the process if anybodys interested.
