I could buy either of those explanations. It can be seen in the original picture, its just a loop of plastic, and I have not even looked it it closely.
Here is another picture of the interior, some of the guys wanted pictures of my spraying the hard plastic parts with base coat paint. Well, I did it and it seems to be OK. THe panely were not in great shape to begin with but most eyes will be on the seats, and they look great. I think the base paint (w/hardener) is a lilttle more durable than SEM dye although it was not cheap ($93 a quart w/accessories) and more of a hassle to spray on.
