I used a junkyard '76 Monte Carlo pump & brackets, & a junkyard '75 Firebird gear when I converted my '72 Nova. I used the rag joint that came on the Firebird gearbox, & I used a new pitman arm & hoses (both listed for '72 Nova w/PS).
The gear had 4 mounting holes, but only 3 are used on a Nova. Many other GM car gears will fit, but there are some differences in the internal steering stops (mine stops when the tire hits the subframe), & in the hose connections. GM changed the hose end configuration from flare to O-ring after '76, but adapters are available, or you can have a custom hose built at a hydraulic shop.
For the pump, be sure you use bracketry from a long-water-pump engine ('69-later cars, '73-later trucks). Some have a short bolt that goes into threads in the water pump, but some use a through-bolt at the same location (driver's side of water pump). I had to adapt mine, but I forget which way.
Factory cars with PS & air have a 3-groove crank pulley. The alternator belt goes to the rear, the PS belt in the middle, & the AC belt on the front. Alternator & PS belts both go on the water pump pulley, AC does not.
