It looks like they used some additional washer/reinforced plate underneath too. That is interesting. I have not seen that before either.
Thank you.

From underneath (left side):

Take a close look at the two hat-shaped "stiffener" locations. There are TWO holes...the "thru hole" for mounting of the bucket seat frame and another hole blocked by the floor panel. This isn't readily apparent in the pictures I posted yesterday for the right side, but they are there!

================================

The factory used this style nut in case you were wondering:

You will need a deep 1/2" socket to install them.

Extra holes covered up by floor panel.

DeltaV has things pretty well covered. Need any other pictures? Just seen this.

I believe that is the shadow left behind when they undercoated over tape, labels, and etc. It's been a long time since I first removed the buckets (some of the undercoating peeled off), but there are no other bagged-and-tagged seat/interior parts.

I'll check my parts book and get back to you.

I’m like the guy that has never had a virgin. Every car that I have owned had many previous owners so I am not sure if what is original in some instances.
