Fox body Mustang seats fit pretty good, they are cheap and easy to get. You're
not going to get anything other than a early A seat to just bolt in place. You'll
have to mess around a bit and drill new holes if you want to go that route. Amazon and Summit
has lots of cheap buckets, I put a set in my 66 cuda. They are very comfy and
lightweight. Cheapest way out is junkyard.
