Exhaust manifold studs?

In attempt to find/fix an exhaust leak from the exhaust manifold I removed the intake and exhaust manifolds to replace the gaskets and the metal ring at the exhaust pipe. However like everything on this truck that opened an entirely new can of problems.

I was able to replace the temperature sender and wiring, however once removed i found the exhaust manifold was cracked in multiple places and that the spring loaded door was wired open. While trying to separate the manifolds the exhaust split into multiple pieces along the cracks i found. Did some searching and multiple sources said that Dorman's 674-173 was the correct replacement. It arrived yesterday and the Dorman doesn't have the same two studs that go thru the intake manifold.

Can anyone confirm wether this is the correct part and/or what bolts i can use in place of the studs? or even where to buy studs i can install?

Anyone have a decent condition exhaust manifold sitting around for a 1965 F100 300ci?

While removing the manifolds i found one of the bolts and washers that secures the manifold to the block was missing, any idea where i look for a replacement?

As always i appreciate any advice

You mean the studs that go into the two holes atop the manifiold, as in the pic above? This is from the Dorman link you posted. Sorry, but I don't understand the problem. You say the "Dorman doesn't have the same two studs that go thru the intake manifold." Did you remove the studs to separate the intake manifold from the old exhaust manifold? If so, I'm guessing they twisted off and stayed in the old manifold. They almost always do.
