If no luck here, try Bill E. w/Supercoupe Performance. I don't know if he would have any LX seats, but
I do know that he has several sets of Supercoupe front seats, a friend of mind ask about some not to long ago and I called up Bill E. and he has Like 5 sets of front seats he said. Both Leather and Cloth seats, not sure on colors and conditions of seats. Call him.
Bill's # 1.513.697.6501 Cinci, OH. just minutes from you too.
Hey, just tell him I sent you to him. Hope this helps!
