Saw this on local Craigslist, located in St. Pete.
2003 mustang mach 1 low miles
Sounds like it might be a good deal and can probably talk him down a bit. If he sends pics I'll post but here is some extra info he sent when I inquired.
Yes it has an eaton swap from a 04 cobra. Its the stock pulley setup at 7 pounds it made 397. It has a bassani x pipe and borla stingers and a mgw short throw shifter. I also have afs deeps dish 10.5 wheela out back with 315s. Car runs great but im moving for college and im worried i cant affors it there. I can get some more pictures tomorrow
