I just cut the crossover tube between the exhaust and intake and brazed in an appropriately sized bolt to close off the tube end. I then cut off the injector rail and brazed shut and reinstalled each air injector. This saved me from having to find the right covers and or plugs. Someone mentioned the air injectors can be plugged with a spark plug. I dunno, never tried that. My "cut and braze" method worked just fine on my truck.

I am sorry. I accidently also included information on removing the air injector rail. That is only necessary if you are deleting your smog pump. I did my egr, smog and new carb all at the same time. I forgot they were separate systems.

Please don’t cut the EGR pipe if it comes off without too much issues. We in California are in dire need of them, I don’t need one but I buy them as they come up and when someone needs one to pass smog I sell them for what I paid for them.
