1964-67: Same BLACK screws & U-nuts for Wiper Grille & Rocker Molding Retainer strip?

[Scott S.]

The three vendors I checked all show 12 chrome or cadmium plated screws for the rocker molding retainer strips (1ASM-F4, Item 3), but the 1964-1967 AIMs all show Screw #3848300, which is the same Screw used on the wiper grilles (1ASM-F1). The eight screws for the wiper grilles are black (so says the 66 & 67JG). The three (suspected originals) I have measure #10-16 x 9/16", with a cross-recess pan-head diameter measuring roughly 5/16", equivalent to a No. 8 head if I have that figured correctly.

The U-Nuts for both the rocker molding retainer strip and wiper grilles are also the same, p/n 3846854. The U-nuts that I suspect were original have a rounded shoulder near the top on each side, but the vendors offer both rounded and right-angle/square cut versions.

I called one of the vendors, they were aware that the same Screw part number was used in both places according to the AIM, but their research showed that the rocker molding retainers used the chrome or Cad plated screws on original cars. The Judging Guides make no mention of the screws securing the retainer strips.


Does anyone know for sure which screws are used for the rocker molding retainer strips, 1964-1967?

Does anyone have a picture of an original 3846854 U-nut, to show the original configuration? John H. posted a picture in an old Thread, but the picture is no longer there.

Hi Scott,
Here is a photo of the 8 "U" nuts that came off my '64 cowl vents. Although not clear in the photo they are black phosphate. The grills were off the car and the screws were missing. I believe these are original "U" nuts.

I don't have any photos of the rocker support strips. I may have made notes when I removed them. I'll take a look. I recall that they were very corroded. Since they are behind the rockers they won't be visible. I replaced all of this hardware recently with LIC parts. Their "U" nuts are the correct shape and black. The screws are also black to correspond with the JG. Their screws for the rocker support strips are cad plated and #8 x ~ 1 inch. I can remove one to measure if you need to know the exact length.

Doug,

Thanks very much for the picture, those are exactly the same as the (presumed original) U-nuts I had at the wiper grille vents and the rocker panel retainer strip U-nuts. Some of the vendors have different clips, they are not curved near the top like those in your picture, but cut straight across and then straight up.

LIC must have changed the style of U-nuts they sell. The pictures on their website look like the ones you posted, which is why I bought them. I bought a set of 12 for the rocker panels (14-06), a set of 4 four the fuel door bezel (05-04), and a set of 4 for the rear body mount access covers (53-05C). When they arrived, they all had squared-off shoulders.

Doug,

exact same part number as the black phosphate wiper grille screws (see pics below).

Same screws and U-nuts used in both locations, but the screws are black phosphate for the wiper grille and Cadmium plated for the rocker panel retainer strips?

Hi Scott,
LIC didn't change the "U" nuts. I went back to the garage after seeing your display. The grills were on the car when I looked earlier so I took one off to have a closer look. They have the square corners.

Thanks for checking Doug, I appreciate it. The CC website pictures show that they have the rounded-shoulder clips, I'll try them next.

About the screws for the rocker panel retainer strips, I suppose it doesn't really matter since I don't think they're visible once installed, but I am curious just the same. I wonder if typical factory production was to use Cadmium plated screws for the rocker panel retainer strips since they ought to provide better corrosion resistance, even though the AIM says to use the same screws as used on the wiper vent grilles, which we know are black phosphate.

Screws for the rocker retainer are black. The screws are special...they have a unthreaded section at the top that prevent overtightenenig and damage to the glass. And the u-clips have a P stamped on them

Rich,

Are the correct screws for the wiper grille also unthreaded at the top (same as the rocker retainer strip screws)?

Both screws have the exact same part number in the AIMs, and both locations share the same U-clip part number as well. I'm trying to understand whether the assembly line deviated from the AIM on this application, or what the discrepancy might be.

Do you have any pictures of the 3848300 Screw or the 3846854 U-nut?

Wiper grill screw is the same. I will post pics of both later today.

When you have time to post them, please do!

Guys,
I'm in the process of reassembling my car ('64). I am finding that the "U" clips I bagged and labled as I took things off the car all seem to be the same shape as what we have discussed. The "U" nuts I bagged from the exhaust panel (6 each for mounting of SS bezel where pipes pass through panel) and those (4) that are attached to the vertical center console for attachment of the "radio" side panels, all seem to be the same size and shape as those used to attach the wiper grills. I can't tell yet if the exhaust panel "U" nuts or the radio side panel nuts are black phosphate plated but they definitely have the rounded corners. I'm cleaning all of them in a tumbler now.

I don't know if these are examined closely during judging, but on the chance they are I plan to install the correct originals in locations where they can be seen (wiper grills and exhaust panel) and use the repros where they are hidden (radio side panels).

Doug,

I'm going to try to do the same, reuse originals when possible. The u-nuts on my vertical center console (for side panel attachment) are stamped "P" like Rich mentioned above, I can't tell about the others because of old paint and/or corrosion.

For the record, both LIC and CC picture the CORRECT u-nuts on their website, but they both ship the squared-shoulder u-nuts ($20+ down the oblivion hole on stinkin' u-nuts). Paragon shows square-shouldered u-nuts, maybe that means they ship the rounded ones.

I'd just like to receive what is advertised, and put the car back together like it was originally. Is that so wrong?

About judging, I think that's the best opportunity to get an objective evaluation of what still needs to be corrected, if the goal is to restore the car to as close to original as reasonably possible. If you have original wiper grille and/or rocker panel support strip screws, could you post a picture of them?

Re: 1964-67: Same BLACK screws & U-nuts for Wiper Grille & Rocker Molding Retainer st

For reasons unknown, all of the vendors offer black wiper grille screws, and none of the vendors offer black rocker panel support strip screws. The AIM says they are the SAME part number.

I would just get 2 sets of wiper grille screws (16 screws, need 12 for the rocker panel support strips) to use on the rocker panels, but Rich mentioned an unthreaded portion which was designed to protect the fiberglass, if I understood correctly. The wiper grille screws on the vendor websites don't have an unthreaded upper section.

Here is a sampling of the available rocker panel support strip screws, all cad or zinc plated, some with attached external-tooth washers, some with separate external tooth washers, and some with no washers, at all. A fine mess.

Hi Scott,
The grills were present (behind the seats) but not attached when I got the car and there were no screws present. The rocker support screws were so corroded that I had to cut most of them off. None remain. Sorry. Doug
