Does anyone know if there is a source for the bolts with the large cup washers for the rear fenders?

Good substitutions?

Post a picture. What about using fender washers?

Sorry, I know what you are referring to. I have never seen them for sale. Let's see if some one comes up with a source.

EDIT: I SEARCHED AND SEE THAT YOU HAVE A SUBURBAN. DISREGARD THE INFO BELOW WHICH IS FOR A PICKUP. Looks like the part you need is a combo bolt and lockwasher (GM #3676478 in the Factory Asssembly Manual)

This is probably not the parts that you need, but just in case they are ...

Lonnie,

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.

Wasted some more time searching. Nothing good ...

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.

Other info:

#3676478 BOLT ASSY w lock washer 5/16-18 X 1
Shown on Sect 11, Sheet 20.00 1947-1954 FAM
'29-'54 MPC Group 8.206 Part 3676478
GM Parts Wiki 1
GM Parts Wiki 2
Chevs of the 40's lists the part number, but it is not the correct configuration

Mine are not clutch head bolts (I dimly recall).

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.

The third photo shows the stainless-steel fender washer I use between the original bolt/washer and the Suburban body.

Thanks for all the searching guys. 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.

Looks like newer style body bolts would be a good substitution.

Dorman makes these. . . . .

Your bolts look like what I had thought my bolts looked like, indented/recessed hex head.

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.

If anyone is a stickler for originality, I have a few of these that came off my '53 panel. 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).

dh53,

These should go fast. When they are gone, let us know.

Would interested people directly contact dh53 via a Private Message?
