Early A exhaust manifold questions

If you find some of the early A body exhaust manifolds that use those two "supports", they are tubes with the ends smashed and drilled, do NOT cut them. Seems they are like hens teeth. I'm guilty of making it even harder to find them, doh! Didn't realize they were a rare commodity and had a real bear getting them out of the rusted our hulk they were in, so we "had" to cut them.
