Back from Colorado, and gathered some information from my ’67 there. As promised, Richard, I took some pictures of my Trunk and Rear Quarter Extension Moldings and their attaching parts.
First, a little refresher. I purchased my set of moldings (Trunk and Quarter Extension), from my Ford Dealer in the early 80’s. Unlike Richard’s sets that he purchased in the late 70’s, mine came with all of the attaching parts. Mine were for a Convertible, which carry the same part numbers as for a coupe. And finally, these are Service Parts, not Factory Assembly Line originals.
That all being said, the first pictures are of one of the Quarter Extension Moldings and its attaching parts. Note that these appear the same as those previously Posted by Richard; nylon retainers with metal studs and cad plated, open hex Pal nuts. The next pictures are of the Trunk Molding with its retainers and the “questioned” acorn nuts. As can be seen in the pictures, these are the stamped steel type of acorn nuts (377522-S100). While it has been over 30 years since I installed these (as the age and weathering shows on the attaching parts), as I remember, the stamped acorn nuts were “gold” tinted cad plated as opposed to the “normal “silver” cad.
Finally, getting back to Angela’s original question of this thread; the nuts for the molding at the corners of the Trunk on a Fastback. While Coupes and Convertibles use 9 of the same Retainers and acorn nuts for the 3 pieces of the Trunk Lid Molding, as, I believe Richard noted, the Body Assembly Manual shows that for Fastbacks, they use 7 of a “push-in type of Retainer (shown as “M”), and two others, “D” that are similar (“Typical”) to the “C’s” used on the Coupe and Convertible (see copy of the Assembly Manual attached). While the “D’s” are shown as “Typical”, they don’t specify the method of attachment.
This is one of those cases where I believe the answer can be found by checking the MPC. In both the 1960-68 and 1965-72 MPC, under “42512-3, Molding, Luggage Compartment Door”, both show for Model 63 (Fastback), 67/69 (the 1960-68 MPC shows “67/”), Part # C7ZZ-63512-A, and below that notes that 2- No. 8-32 Nut and Washer Assy, 377523-S100 are required. To me, this indicates that the fasteners for the “D” Retainers must be these 377523-S100’s. In checking this number in the “Standard Parts & Utility Catalog”, one finds that it is a stamped Pal nut with washer (see picture). While this is contrary to what Angela noted that it seems that this location should probably have the stamped acorn nut, this seems to note otherwise.
Hope that this has helped clarify some of the ‘mystery”.
