bucket seat measurement needed
just FYI Once you get measurements from a-body seats and find your alternate seat bases are 2 inches wider, you still wont know for sure if they fit or not.
I put 67 fury seats in a 67 cuda once. They fit good enough except the console prevented going forward the full distance and the seatback wouldn't fold forward without the door open. They were too close to the door and armrest.
Good luck
