there is no kit for the 97 body. you can put one on it just wont fit as good as the 99-04s. shouldnt be too hard. just line it up, hold in place with tape and screw it in.
damn im in the same boat as you, i also have a 2000 gt and owe roughly 13k. 71,500 miles. i really wanna trade mine in for a newer 5spd. if it would make you happy go for it.
What are the best headers to put on my gt. its an aod so the bassani mid-lengths are ruled out. i dont want shortys (drone).
