Topic: fastback deck lid molding hardware: "Acorn" nut at corners?

[Angela]

Is there supposed to be one acorn nut at each of the corners of the deck lid modling on fastbacks, as there was along the entire trunk lid for body style 65? The molding hardware protrudes into the trunk in the two corners and therefore I suspect the acorn nut was originally used in these two locations on fastbacks as well.

If yes, I'd assume it's the same acorn nut as found on coupes but I'm not sure.

Does anyone have a picture of said "acorn nuts"? Obviously, I can look at AMK catalog but I would like to see images or pictures any original examples from a convertible or coupe with the exterior decor group please.

One acorn nut at each corner is correct.  The technical term Ford used is a "stamped nut".  Attached is a picture.

In between the decklid stamped nuts at each end, the inside is non accessible.  So in lieu of nuts there are plastic push pin type connectors that expand in place to keep the molding in position.

These nuts were also used for both quarter panel end cap extensions, I think 3 each.

First, I revived this thread because so much of the information is similar, maybe making it easier for future searchers to find the answers they might need.

1967 Body Assembly manual page 36 shows images for body 65 & 76 (coupe/convertible) different than for 63 (fastback) for attaching these decklid moldings.

NOS quarter extension moldings come with 3 retainers each and include the attaching nuts however Ford, in their infinite wisdom did not include (ever to my knowledge & experience) include the molding clips or nuts on their coupe/convertible decklid molding.

Acording to the Osborn Assembly manual, Coupe & convertible decklid moulding clips are said to be different than the quarter trim moldings as well as the nuts used to secure them as being different (crown nut 377522-S100 ~AMK B12938 page 70)

I am simply trying to get the nuts correct on the visible trunk lid for my Coupe before I get to paint. If somebody can shoot an image of their "known to be original" style molding nuts, that would be great!

One more thing, and the reason the original poster asked...The assembly manual says the nuts were "typical" of what used in the same location as coupe/convertible decklid molding, this would be for use on the end of the decklid molding for body 63 (fastbacks) so John, are you sure the stamped steel version are correct? I ask because the image posted does not match the assembly manual.

Engineering numbers gleaned from the assembly manual regarding ALL of the retainers, best I can decipher (please correct me if wrong):

*DECKLID & QUARTER EXTENSION MOLDING RETAINERS & NUTS
                Fastback
                         retainers ~decklid molding-outer (2 reqd.)~ C7ZB-63291B80-A (nuts: says typical of the 377522-S100, also AMK B-12938)
                         retainers ~decklid molding-center (7 reqd.) ~C7ZB-63425A88-A (does NOT require any nuts)
                         retainers ~quarter extensions (6 total reqd. both sides) ~C7ZB-63291B80-A (nuts: 45203-S36, also AMK B-12940)
                Coupe and Convertible
                         retainers ~decklid,ALL (9 reqd.) ~C7ZB-6542533-A (nuts: 377522-S100, also AMK B-12938)
                         retainers ~quarter extensions (6 total reqd. both sides) ~C7ZB-63291B80-A (nuts: 45203-S36, also AMK B-12940)

Richard, the Jan 67 MPC lists the following:

42512-3 Moulding - Luggage Compartment Door - Included Attaching Parts
F (63) C7ZZ-6342512-A
F (65, 76) C7ZZ-6542512-A

This MPC won't be of help I'm afraid because the darn fasteners were included.

I did find the following picture in the shop manual, page 17-34.  It shows that the fastback ends, and the coupe/convertible length, uses a "crown" nut (better for looks and/or anti-snagging) instead of the stamped nut used on the quarter panel extensions.

I'll check tonight.  But I put on an NOS deck lid moulding on my car in 1980, and that of course may very well not have been with "factory" type fasteners.  I'm sure there are plenty of pics of unrestored cars out there - but something that covers this detail might only be in Jeff's files.

John, Thanks for your input. I know just one thing about 2 different NOS Coupe decklid moldings I have bought before. FIRST time I bought the trio of moldings for my coupe from the local Ford dealership, back in 1979, So.Calif. The trunk lid molding came w/o the clips (the extensions WITH the clips) and the trunklid ones were AT THAT TIME available separately. (didn't know they were NOT included till after I opened the wrapper) Bottom line, after I called them to see why I did not get new retainers, I simply ended up using what I already had at the time. Recently, I bought another trunk molding and a pair of quarter trims and recieved the same retainers...6 for the quarter trims and NONE for the trunk molding.

See if these will help. Of course for details on the parts listed, you'll need the Standard and Utility Parts Catalog. If you don't have one and need more detail, let me know and I'll look them up.

Thanks also Bob, your images indicate that the retainers, though listed as different in the Assembly manual, it looks like they combined the retainers for service parts at least or changed before or along production to a universal retainer for all locations (C7ZZ-63291B80-A).

I see a seal of sorts (gaskets)on the retainers I got with the latest NOS quarter trim moldings and the same seals were present on the replacement set I had previously installed on my example back in 1979 on the retainer's studs.

Question: I know I ought NOT assume anything ever but maybe the differences were whether or not the retainer had these "seals" used on them as the "why" the assembly manual has different numbers listed for use on the decklid molding. Maybe?

[196667Bob]

Richard : The images I attached are from a December, 1967 printing. The nuts for the "C" fasteners are #8, stamped acorn nuts, and those for the "E" fasteners are 8-32, stamped flat hex nuts. Neither shows any sealer, although in the illustration of the "E's", it looks like there may be some included with the nut.
I too, put a set of these that I bought from Ford, on my Convertible in the early 80's. As I remember, the "C's" were stamped acorns; don't remember about sealer or the "E's" for sure. However, I just recently removed all the moldings in going through my car to get it ready for painting (still a ways off). I stored the moldings with the fasteners attached. Unfortunately, my car and parts are at our Colorado place, to which we won't be returning until March.
I'll put it on my calendar to take pictures, etc. then; maybe John can shed some light in the meantime when he checks his.

Point of clarity of "where" the seals or gaskets are.
The seal or gasket is against the plastic retailer, slipped ONTO the stud protruding from the retainer...seal (or gasket) is NOT on the nut itself.

By the way, the image below is of the nuts that would be used only on the end cap moldings, NOT the "ACORN" type initially being discussed.

Using the retainers pictured below WITHOUT the nuts, total of 8 would be used on fastbacks. Two acorn nuts used on the fastback deck lid molding PLUS 6 nuts (as pictured below) required for the quarter extension moldings (3 each side).

The retainers pictured below WITHOUT the nuts,a total of 15 across all three moldings needed on Coupes & Convertibles, there ARE ACORN NUTS ONLY USED ACROSS THE TRUNK MOLDINGS (not pictured below) SO A TOTAL OF 9 ACORN NUTS ARE NEEDED along with 6 of the style of nuts pictured below for these coupes & convertibles.

For the record, an acorn nut is capped, no threads show thru when used.

NOW, using all of this discussion as a platform...back to MY ORIGINAL QUESTION.

Does anyone have a picture of said "acorn nuts"? Obviously, I can look at AMK catalog [or Ford parts/assembly/service literature] but I would like to see images or pictures any original examples from a convertible or coupe with the exterior decor group please.

Well I struck out on my end.  My 1980 NOS part purchased and installed in that year has stamped nuts.  No crown nuts (Term Ford used in the 1969 fastener book, the term "acorn" not used).

I had a coupe deck lid that was scrapped a few weeks ago - lots of dents, a little rust, not worth saving.  No pics of this area.  Then I went through a couple hundred reference pics, but none showed this area.

Ahhh NUTS! I appreciate the effort though John.   You might think that in Columbus last year and after looking closely at 3 convertibles, one of them that we judged together and taking countless pictures of details relating to trunk lamps on the two 67 convertibles, that one of us might have snapped a shot at one of these nuts! I am going with "sour grapes", those three examples were restored so they probably were not correct anyways

After all these posts, I went back to the 67 Body Assembly Manual and did a review. The Fastback trim is poorly documented but the two end nuts, 377522-S100, are "implied" on the drawing, not in the bill of materials. I have added them to my hardware spreadsheets. On that, thanks.
Based on Ford's finish suffix, -S100, AMK's advertised finish suffix, -S36, and the trunk application, I would assume that the nut is gold zinc with a sealer (to reduce exhaust fumes in the trunk). AMK apparently sells the nut without sealer, but does sell a mastic sealer separately (2014 cat, p167 AMK B-11245). That combination may work.
Richard, why do you want a picture? The assembly manual show it, albeit poorly done. All a picture will show you it's location, you will have difficulty determining size. The only usable external reference is the hex size, and as it is 11/32, very difficult to distinguish between that size and 3/8 hex.
