The panel-body rear-fender bolts and washers are completely different from the pickup's. They are not typical fender washers and the bolts are indented hex head without flange.
If Snubby does not post a few photos, I'll take one off my Suburban and post a few photos.
The bolts are available (even stainless from Totally Stainless); however, I have never seen the heavy/thick cupped serrated/starred washers for sale.

I found one source for #3676478: Collectors Auto Supply $3.00 ea Part numbers listed in order Description says "Clutch Head Bolt" and does not mention the lock washer. The diagram in the FAM shows a hex head bolt.

I'll see how easily I can take one off to photograph.
Some of those part numbers are surely correct.
added in edit:
I was wrong about the indented/recessed hex head. It is a plan hex head bolt (they are captive with the washer and are not stainless, so I do not think that I changed them).
I have photos that I will post in about an hour. I have to take my daughter to her wedding shower - I was not invited.

Yes, suburban/panel rear fender bolts appear to be quite different than the trucks. Which makes sense, given the difference in the way it mounts. Here's a photo that shows what I believe to be original parts. I don't believe this has been removed. I've also taken a fender off another panel that had these very same bolt/washer combo.

They are available without the flange.
Even if the flange head bolt or the original washer is used, I like to spread the pressure through a fender washer.

PM me and I can give you more details. No they are not new, but they might be useable, and the price is right (free). | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | dh53,
These should go fast. When they are gone, let us know.
Would interested people directly contact dh53 via a Private Message?
