There is a bunch of options you can go to. Your best bet IMO is to got to someone like Vintage Air, or HotRod Air. Zoops also makes an excellent line of quality brackets. Most of the brackets have been developed for street rods which almost always use the short chevy water pump due to clearance issues. So just about all their brackets are for short pumps. Vintage and Hot Rod Air both have brackest that bolt only to the water pump and intake manifold. Theses are for the early heads, or a situation where you wish to keep the accessories in close to the engine.
