One of my flight instructors used to restore mustangs and pointed me to this junkyard where he unloaded all his parts when he sold the buisiness. Its in Kingsville, Texas. Called Camarillos. Two bus loads of parts. Some good stuff.
its about 3 hours. I got my engine from a guy there so Ive made the drive once. Not bad. If you let me know what youre looking for I can see if they have it before you make the trip...
