That P/S bracket looks broken...
As many pictures that I took of my 77 build, there were no complete motor accessory pic's. Here is what I had:
Regarding the Alt, do you have an air pump/smog pump? The top bracket is different for that. It is cast rather than stamped steel. If you have the smog pump then the Alt would have a dual pulley. The Alt belt is driven by the crank and water pump, with the smog pump driven off the Alt.
No smog pump, then you have a stamped steel bracket, two bolts on the water pump, single pulley, and the alt is driven off the crank and water pump.
It is a little more involved with the smog pump as that bracket also bolts to the head and there is a belt tensioning bracket for the smog pump that bolts to the cast bracket.
Oh and I am not running a factory alt, in the picture it is a small case G3 Alt rated at 90 amps
