Smog Pump?

I have a 1995 Pontiac Firebird 3.4L, which I just bought it.

I tried to get it smogged here in Cali and was told it's missing an air injection pump, which from what I can see online, is also called a smog pump.

I can't find any for sale in parts stores.

I went to a junkyard, and every six cylinders were missing the pump.

Questions: Does the 3.4L typically have a smog pump, and if so, how do you plumb it into the exhaust system?
