Fuel Rail / Upper Intake Bolt/Stud

So I've managed to do my valve covers and a few other odds and ends.

The problem is, one of the six bolts that holds the fuel rail down and acts as a stud for the upper intake nearly welded itself with rust to its mount. When I began trying to work it out the tip of it eventually bent and snapped under very light torque.

The real issue I have is I'm now putting it all back together and can not find a spare.

The dealership scoffed at me for even thinking they would have a Mazda truck bolt, even after a detailed explanation that I'm working on a Ford scripted engine, etc.

Lowes, NAPA (We have a distribution warehouse here.), Fastenal, and other local specialty stores can not locate it either.

Before I hunt out a junkyard and pick-a-part, anyone have any other suggestions?

We can't even locate a part number or proper terminology for the bolt/stud/fastener.

They are a discontinued item, so unless a set pops up on ebay you are out of luck.
Or if wrecking yard has one

I would take one of these studs down to machine shop and ask how much to duplicate.
Basically it is just a stud with a washer welded in the center, and there are studs with shoulders like that for other applications.
Machine shops make things like this from scratch if needs be, but I bet they will know of something similar they can adapt.

And I would think you could get away with just the correct size stud without the shoulder.
After all when you tighten down the upper intake it presses fuel rail down against lower intake.
fuel rail's stud/shoulder is 11ftlb torque, upper intake is 14ftlb so not talking about alot of pressure here.
