I have a 1990 YJ with seats that were swapped in to convert the interior from spice to black. The only problem is that I don't know if they are YJ or CJ seats. I bought some Coverking seat covers to fit non-reclining seats, and they are too wide at the seat back. Does anyone recognize these seats? They are 18" wide at the widest part of the seat back and are one-piece, non-reclining.
