Here's an NOS one on eBay:

Thanks Royce were does the grease cup go?

The roundish with legs pair go between your front hub bearing washer and the dust cap/cover


Lots of those tossed over the years when bearings were replaced or packed

Thanks Jeff I have never seen them before

Ford Car Parts (aka the MPC) is not really a good source to determine body or interior hardware part numbers or finishes. Ford dealers could not stock all the different pieces of hardware used on the assembly lines for all models of cars and trucks (include Mercury), so what is shown in the MPC is what works, and not what was originally installed. The exceptions are engines, transmissions and differentials internals, and that is not an absolute. The best source (and that is not always true) for hardware parts and finishes is the Osborn Mustang Assembly Manual. What is listed there is what Ford Engineering intended to be used, and that was subject to assembly line procedures and availability. (Note to Cougar owners, a lot of Cougar stuff is in some of the assembly manuals.) Thanks. The story behind the spreadsheets is simple. I went to a local Mustang shop (now closed) and told the counter guy I needed, "one each of the bolt that held the clutch return spring bracket to the brake support on a 66 Mustang GT Fastback, four speed". He said he had no idea what it was. Well, he didn't, but I decided to find out. That was over 25 years ago. The Osborn Manuals made it possible.
OH, the bolt I needed (technically, it's a machine screw) is 43490-S8, 5/16-18 X 3/4 Hex, split lockwasher, clear zinc plated. AMK does not carry that exact bolt.

Thanks Jim. I was getting confused as the Osborne Mustang Assembly Manual has different finishes listed than the MPC. I will go with the Osborne info, but I also noticed that it does not list finishes for all of the fasteners and clips etc, so I will have to post and ask questions to confirm as the Osborne manual does not show finishes for all of the fasteners.

In the library, check out "Mustang Hardware Spreadsheet 67-68", both files (by part number and by application). It may answer part of your question.

So does the Library, trump the Osborne Manuals?

Let me "enlighten" you. First a question, did you read the first entry on the thread? If you have not, I suggest you do. If you have, reread it.

- yes, and you will be abiding by it.

Yes I did read it Jim, But I wanted to double check to make sure that I finish my fasteners correctly, and there are several sources of information out there that people are using. I am just trying to boil it down to the definitive source. Your help is appreciated, but I do find some gaps and some fasters I have been unable to trace to any source.

List them. I've made several corrections to the spreadsheets over the years based on forum members queries.

If possible, by part number please.

Hi Jim here is my first question of a fastener that I can't find the correct finish for. Perhaps I am not cross referencing correctly, and that would explain why there are some fasteners I can't locate.

359662-S

I am looking for the shock tower cover bolts and nuts. I found the part number in the MPC, but could not find it in the Osbourne manuals or on the spreadsheet. This is just once such example of the issue I am having cross referencing.

Thanks

[bullitt68]

If possible, by part number please.
Jim

Hi Jim here is another example. What am I missing?

354530-S

I am looking for the Differential U-Bolt nuts. I found the part number in the MPC, but could not find it in the Osbourne manuals or on the spreadsheet.

Thanks

Hi Jim scratch that on the shock tower cover (378178-S39). I found it in the Osbourne Body Manual and was able to cross reference it on the spreadsheet. I see what you mean about the MPC now.

354530-S

I am looking for the Differential U-Bolt nuts. I found the part number in the MPC, but could not find it in the Osbourne manuals or on the spreadsheet.

In what document did you find this nut, 354530-S? All I can tell you now is it's a 1/2-20nut, 0.560 in thick, 27-32 hex drive, nylon locking.
Remember, the rear axle was installed as a sub-assembly, assembled in another plant to its own set of documents. As such, the assembly line drawings would not apply. The same goes for engines and transmissions. For sub-assemblies, the MPC is the only source for hardware, and I have used it to document those types of items. In many instances, the MPC does not list finish, as the item is supplied to Ford Service Departments in one finish only. This was to reduce the number of inventory items.
