Two barrel intake 66 slant six

I have a 1966 Plymouth Valiant slant six with a single barrel intake and I’m looking for a two barrel intake. I’m located in Cleveland Ohio.The carb I have is missing a couple of parts and has been cobbled together, and I can’t find a good replacement. So I’m trying to see if I can upgrade to a two barrel which there are many more of those around to purchase. Please let me know if you’ve got a two barrel intake for my 66!
While you're right about the two barrel carburetors maybe being more available, the intake manifolds certainly are not. If you're good at fabrication, you might try what dan posted.
