Anyone have a carb base?

I pulled my carb off the swamp monster with intentions of doing a rebuild on it today. It was going well until I got to the base. The rod that holds the linkage and butterfly were seized enough that I accidentally twisted the rod that the the butterfly is attached to. Then I thought i would take the butterfly off and see about punching the rod through to clean it up. Lubed everything up like crazy but both screws fastening the butterfly snapped off.

Long story short, I wanted to check to see if anyone has a 1 barrel rochester lying around or at least a base that they would part with. Eventually I'd like to go with something different but that will be down the road.

Thanks
