Pace Setters are what I have, but you can find a larger assortment at Automotive Customizers and just about any muffler shop can do the work for you. They will probably have to drill out broken manifold studs from your engine block and retap the holes afterwards. That is the most expensive part of the manifold saga. Headers are a better solution than just replacing the manifold again. It is cheaper and you will gain more horsepower, better fuel economy, and it will sound mean too. Good Luck!
