I know that you said you got new hardware from AMK but the bolts I have seen do not have the large washer. Like the ones in Jeff's pictures. Maybe it is a plant thing.

+1 Think what you found was likely from a prior repair or remove and reattached

Hard to tell in the photos Jeff posted, but the head marking look like the AMK bolts, except it appears that they also have the large washer

The two (the fender bolt and the one from the unrestored San Jose example are very different

Fender washer has a separate though captured washer that is larger than the original bolt shown. The bolt from the San Jose car has a flared base but no washer and the head design appears to be the RBW one

Notice the comparison of diameters in the pictures below

The bolts in the AMK kit are not fender bolts. They are shorter bolts that have washers similar to the fender bolts. They are typical of Dearborn, not so much for San Jose manufacture.

Good point. I will have to see if I can find some bolts like that.

Would these bolts be a better option compared to the other examples I posted

Possibly not. Those are Grade 5, the "Y" marking on the head. Previous shown bolts were Grade 5.1, the "T" marking (it's actually and inverted "T").

Those seem to both be marked "T".

These are what I have use from AMK in the past. You cannot see it in the picture but there is an anchor on the head.

Those "T" (there are two) is/are manufacturers logo's. Each, including the "C', are in a "Y" pattern. I strongly recommend you review bolt head markings. Try the library.

Do you have a photo of the right bolts?

Well I have anchor head bolts. I will check my AMK catalogue

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

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.
