you can put a 68 seal in and use the 68 chrome and clips.
The 67 seal will be out soon, I receied an email the other day that is done and will be shipping soon!
actually the Paddock had no full sets of seat cover in stock. they had all mismatched sets and oddball colors. i will try to get the list posted in the next few days.(if it does not cut into my hunting time)
