There are some pretty major differences here. The hood is very different between a 2004 Mach 1 and a 99-01 Cobra. The Cobra has a reverse scallop faux heat extractor that is recessed, where the Mach 1 has a domed hood similar to the 03-04 cobra to clear the shaker scoop. That and the front bumper lower valance is drastically different. The Cobra has gill type fog light opening and flares up higher. The Mach 1 has the GT front bumber valence. As for the wheels I imagine you could use something like Pegasus tires with the spun aluminum wheel barrels (sleeves I think they are called) with a Magnum 500 wheel which would give the look but still would be a little deep compared to the shallow factory Ford rim on the Mach 1. I have pictures but I do not have a Photo Bucket account. Not sure how to post them otherwise
Edit... I bothers me that there have been so many great Mustangs in the past 10 years and just a few have been kitted. Wish they consider modifying the tool for the 99-01 style Cobra to a Terminator 03-04, and a Mach 1. Also waiting on the "new" (since 2011) 5.0 in kit form, maybe even a Boss 302.
