I am installing a new air gap manifold on my small block. The alt bracket does not work because the water goose neck is 1 1/4" taller than a stock manifold. I also have vortec heads but everything seems to fit ok on that end. It looks like they have a tapped out hole for a bracket in the manifold at the same height as the stock hole however it is a different location, I think I can cut the stock bracket and drill another hole, but I don't want to try it untill I ask someone who has run into this problem before. Thanks for your help!
