Slant 6 225 carb?

I'm in the same boat now. I have the 1971 Dart with the 225 and the Holley 1920. Well today I found a crack in the carb housing and it's pushing fuel out every time it's pumped. Only fix I know of is a replacement. I can't seem to find one worth the money. Rock Auto has some Autoline Reman and O'Reily's has something called a Tomco. Not good ratings on the Tomco and it's a special order. Any other sources you guys know of to find one? I've heard "switch to a Carter" and even some people telling me to go to injection...I'm saying no to that obviously. I've searched online but can't seem to find a 1920 that doesn't need to be rebuilt to start with. Any ideas?

Thanks in advance.
