Altenator and power steering pump options- oh, also water pump

Ideal might be the brackets from a 1978 Volare slant. That allows a modern Sanden AC compressor and Saginaw p.s. pump. The later is more efficient and came in Chevy's, so aftermarket choices. You can buy blingy Sandens. Insure you put a gasket on both sides of the steel plate of the water pump. I haven't read of better water pumps.
