Thanks for the replies. I've determined that a PO has swapped the 66 interior (front buckets and rear fold down) out for a 65 . Guess I'll be looking out for a set of 66 buckets, preferably with the black back. I have a set of blue 66 Dart buckets but am thinking of using them in my 65 Dart wagon as I understand they are narrower than the 65s and I would like to use a buddy seat between the buckets.
