The stud has a part number of 373424-S36 from the Ford drawings that I have for the back up lamp assembly.
Added to my spreadsheet. Thanks.
I didnt really want to add all the part numbers for all the components because I think that would be more information than anyone would really need, especially since you cant order or search for those parts anymore.
That's not exactly true. The nuts and domed/spherical/cup/special washers are available from AMK. I fabricated a replacement stud from a piece of 10-32 threaded rod, dressed the ends and had it gold zinc plated to replace one damaged on a very good quality original from a friends 66 convertible.
A part number provides a common reference "name" to parts. You may ask the guys at the parts counter for something by name, but they will look up its part number. Don't be afraid to use them, even the ones that are obsolete.
While the Ford Standard and Utility Parts Catalog lists the 359972-S8 washer "officially" as "Round", I think that Jeff's notation of "domed" with the addition of "slotted" is more descriptive of the actual part. Thus, I would note it as "Slotted Domed Washer/Spacer".
In a former life, I was involved with Military Logistics (I was a member of the Society of Logistics Engineers) where we cataloged new designed items (part and assemblies) for use in the Military supply system. One of the tools we used was Mil Handbook H2 which covers item description. The guidelines used are to identify an item by what it looks like (simply said), hence - Washer, Spherical, Special. On the other hand, "A rose by any other name would smell as sweet" (William Shakespeare - Romeo And Juliet).
I disagree with statement that 67 and up never had the domed spacer from factory as many if not all 67 and 68 that I've seen do have them installed.
Also called out on back up lights for 67 and 68, as -S8: and 69 and 70; as -S36; and on 67 and 68 Fastback side scoops.
Throughout, the singular word for lens is mis-spelled as "lense".
I should have been an English teacher...sorry.
Your, oops, I mean
you're (a contraction for "you are") correct. It happens
a lot (it is "two words"), mostly in duel, I mean
dual (I don't want to fight about it) uses. Consider the use of proper English (American version) a feature of this Forum.
