Do you have a Ford hardware part number? I recommend that you get into the habit of using a part number. It makes the search by others easier. See attached.

Yes that is what I used. No luck. Could not find it in any of my 3 AMK catalogs

Was the number I gave you not available?

Looks like I missed the number, but I've got it now. FYI the bolt you posted looks shorter than the one in Jeff's photo

I tried cross referencing all of my AMK catalogs and the Assembly Manual etc and have not been able to find a match. I just need to know what the correct head markings are so I can try to source them as they do not soon to be available in the aftermarket

I scanned this thread and NOT ONE OF YOU HAS REFERENCED A FORD HARDWARE PART NUMBER. Do you have "partnumberberphobia"? That
malady can be cured by determining the Ford hardware part number (It took me all of 30 seconds to determine what it was).
One of the goals of this forum is to educate its members. So far, you've not got a passing grade.

Thanks for your great teaching skills Jim. Sorry but it took me a while, as in a few years, but I think finally figured it out. Hopefully this explanation will help others. It sure would have helped me, or those of us that need things spelled out!

In the back of the AMK Bulk Fasteners Catalog, there is a Part Number reference spread sheet listed in order of the part numbers. First You find the part number in question in the Assembly Manual and then cross reference it with the spread sheet in the Bulk fasteners catalog, and it will give you the page number. The lower rad bracket bolt is listed as part number 40923 in the ASM.

Then just go to the page number. FYI it does not always say what the fastener is or manufacturer, but it will show the fastener that AMK has matched to the original part number.



On page 109 there are 2 bolts shown, so not sure which one is correct

This is the one referenced by Ruppstang



This is the other one on the same page, which is what Jeff referenced, so perhaps both are correct?



However this one looks more like the one in Jeff's photo, as the bolt looks longer



I think that it is safe to assume that assembly line workers would or could use any fastener that fit the application based on inventory and availability.

Hopefully I am one step closer to solving the case. FYI I searched extensively and could not find any posts regarding the lower rad brackets bolts, so perhaps this is uncharted territory, but if it helps anyone else in the process it was worth the effort. I know it has helped me. My current work flow ratio = 90% research - 10% wrenching! Which might explain why this project is taking 10 times longer that it should lol

Workers didn't get to choose what hardware that was delivered to their station and it was not normal to just use anything that would work according to workers and plant managers. Of course there were times but those were rare and not typical

Up side is that with good research you hopefully get things right he first time and you don't have to redo things more than once

Yes would be nice to start only doing things one time lol


So would say that the RBW bolts are the correct ones for my car?

So would say that the RBW bolts are the correct ones for my car?

Those are the six bolts that mount the block plates to the block. They are way too big at 3/8" - 18 TPI. The lower radiator brackets are 5/16"-18 TPI. The bolts in the AMK kit are closer P/N B-12565.

Given that is the best information we have at the moment and a great original example of another late 68 San Jose car I would feel comfortable at this point going that direction

Jeff do you have a different part number in mind? The ones he referenced are P/N 375116-S, those won't fit or work.

[jwc66k]

This is the one referenced by Ruppstang[/size][/font]

The screw (conventional wisdom calls it a screw) is shown in the "1968 Mustang Body Assembly Manual" (AM0021) pg 13 (N8-8105-4) as Ford Hardware part number 40923-S (no finish code shown). For 1969 it  is also shown as -S (no finish code) but for 1970 it is shown as being a "-S2" (phosphate and oil).

I think that it is safe to assume that assembly line workers would or could use any fastener that fit the application based on inventory and availability.

Workers did not have that prerogative. Everything was done per engineering and assembly line documentation. Variations, like parts substitutions, needed to have approval of the assembly engineer. There are exceptions of course. Unfortunately these substitutions were not always formally documented. 
Here's what you are faced with: the 1968 Body manual showing 40923-S, or pictures that have no referenced part number. Your call.

It would appear that the only ones that would fit are the B-12565. So while it may not have the correct heard marking it does fit.

Exactly, the ones that I told you would work. I searched the Ford number and the AMK cross reference as you did.
