79 250 integrated head exhaust manifold crack

[79Square]

I'm reposting this thread under engines, since I previously posted under the wrong forum earlier. So if you are re reading this, I apologize.

I have noticed that I have a cracked exhaust manifold for my 79 250 inline 6 with the integrated head. I have searched online, and can not find anything for a replacement. I can find plenty for the NON integrated. Can anyone help on where I can find one? Thanks.

I say that your best bet would be to go get yourself one used off craigslist of from a junkyard.

Most people seem to install swap for a non-integral head, so reproductions don't seem to exist.

I think I'd go to an earlier head, manifold, and carb. But if you want to re-use your carb and keep the engine stock, here's a source. $375 seems like a very good deal.
