Hi all, a guy I know has had a k-code fastback for 30 years sitting in his garage and he's looking to sell. He claims it has all the k-code specific parts, but I'm curious what are some things I should be looking for to confirm this? It's a running driving black fastback so it's not a rust bucket, but obviously not perfect. I'm an early Bronco guy so I'm not as familiar with these Mustangs.
