Topic: Shaker hood trim ring sealant/gasket and speed nut finish

[hopey]

I was reviewing some older posts as well as the Osborne assembly manual and I have a couple of questions regarding my 11/15/69 Dearborn built 1970 BOSS 302. Unfortunately I do not have any good photos of this area on unrestored examples, just the couple of photos attached.

1. Assembly manual calls out item L, ESB-M4G110 black sealer to be applied between the trim ring and the hood. However I personally have never seen any evidence of this. Can anyone confirm whether or not this was present, and what it is exactly as the diagram shows what looks like a gasket.

2. The Pal speed nuts are listed as p/n 382110-S100. No where on the drawing is the finish called out but I believe I read somewhere that the S100 in this case was zinc dichromate with sealant washer. Can anyone confirm?

It is my understanding, and from what few I've seen, that the Ford hardware drawings, in this case 382110, contains the specific requirements for finishes for codes "-S100" and up. Many of these are better defined in the "AMK Products Guide to Ford Fasteners 1955-73", in this case on pg 217, that states "includes sealer". No plating is mentioned on that page. (I still recommend you get a copy of the AMK Guide.)

Thanks I have the AMK guide but could not find it. I will take a look at p217 when I get back home. Edit: attached photo showing with sealer.

If anyone else can confirm via photo or experience on my question regarding gasket/sealer item L as well as the finish on these speed nuts that would be appreciated.

Some pictures that should help give and indication of what the plating might have been or at least what is was not

Also if you look at the nuts in the second picture as there appears to be some evidence of sealer that squeezed through and was at least picked up by the nut while tightening. Also some possible evidence on the back side of the nuts.







Hope this helps

what year/ build plant those photos are from or are they just assorted 69/70?  The sealer was typically integral to the speed nut, as shown by attached photo of some palnut engineering samples I have collected over the years.

I am not very good at determining what you mean by what finish they are not?

Since this is in the 70 section I limited the pictures to 70 examples

Nuts alone in the picture I don't have what reference car they came from

White car was a NJ built car and the red car is one was a Dearborn car

I am not very good at determining what you mean by what finish they are not?

Making reference that by the finish we see on the originals the finish of the nuts were apparently not a finish like phosphate. Appears to likely be a zinc or a brights version of cad

The finish could have been bright zinc or zinc dichromate, that is the typical finishes supplied by Pal. I have samples of both.


Any evidence of a gasket or sealer under the trim ring in your photo library?

Don't notice any gold tint in the pictures I have of 69 or 70's and of very low mileage well cared for cars but flash or angle could always diminish the "look. Didn't post those since they were not well focused and not the focus of the picture

Never seen a gasket or heard of anyone finding on. Don't recall ever seeing except possibly one one, memory is not crystal clear on that one memory, over all the decades of looking at or owning shaker cars. Bottom line I can't confirm that there was a bead of sealant around the whole ring on cars I've owned or on rings I've had or seen for sale over the years. Maybe someone else has experiences to offer

Thanks, I have never seen the trim ring have sealer but my experience is considerably less than this collective group. Possibly just another assembly manual peculiarity that was not implemented on the line.

AMK sell reproduction fastener kit in zinc dichromate finish, but the dimensions of their fastener do not match the Ford fastener manual p217 Jim referenced and I guess I have reason & evidence enough now to question the finish.  My PAL engineering sample kit has several speed nut fasteners that match dimensionally but only a couple look like your photos.

This is the factory correct hardware and finish in my opinion for these shakers trim rings.  This is from a 70 Dearborn car.

Marcus,

Perfect, those are among the ones I was looking at last night!

Have you ever seen any sealer between the trim ring and the hood?

[tgilliam]

Hopey,
I have had access to a few original shaker cars over the years and have not found any sealer on the underside of the actual trim ring or the hood side of the retaining plates on the underside of the hood.
It has been my experience that the Pal nut had a sealer material/washer on them and that is where the sealer comes from that can be seen in some original pictures such as those provided by J.Speegle.
Just a small sample of course on my part but from experience going back into the 70's.
I believe I have one trim ring with the plates that was taken off an original undisturbed car in the garage. Not definitive by any stretch but I can look at it if you believe it would be helpful.

Thanks. I suspected that there was never any sealer but it?s good to have feedback from others! Appreciate your help.

Interesting info, thanks.  Does anyone have 4 original PAL speed nuts they can part with?  My body guy lost the originals....  Alan

Alan, unfortunately I do t have any extra, but if you keep your eyes on eBay the palnut engineer sample kits come up for sale quite frequently. Make sure you can see the nut in the photo as there are many different selections.

Also I think this specific nut was used elsewhere for other trim and moldings, so shouldnt be unique.
