Friend's header install A.I.R question

We are blocking off the EGR and AIR systems, what size brass caps can I get to block the AIR tubes on his headers, anyone know the size? Help QUICK cause we are working on getting the passenger side header in right now.

93-95 use an M22 plug, 96-97 use an M18. You'll need to go to an auto parts store and find a drain plug that fits - hardware stores normally don't carry that thread.

I want to cap off my AIR from my pacesetter headers, the threads are on the outside. What size cap do I need?

For the headers with a cap, I just took one of my AIR valves to NAPA. He matched it up with a brass pipe cap, it threaded right onto the header nipples.
