I took some more pictures this morning, see below. I think that what So Cal Joe is asking about is circled in the new pictures.
I had the passenger seat sitting upside down the rider seat for about a week before taking the pictures. It looks like there might have been a pressure mark from where the front of the passenger seat was resting on the rider seat. It looks like this mark has pretty much reformed now. I'm adding another picture that shows similar pressure marks at the rear of the rider seat, where the passenger seat overlaps and rests.
Joe, if this isn't what you were referring to, let me know.
(Edited to get the right pictures on the post.)
