brass pipe plugs for manifold

I want to remove the air tubes on my stock manifolds and plug them with brass plugs. Anyone know what size to get and where I could get them? It's a 305TPI.

They're 1/4X20 plugs. I bought mine from Ace Hardware, but any good hardware store will have them. Taking out those air tubes made it -so- easy changing plugs that I could've done them in my sleep.

Mine are 3/8" brass pipe plugs with a 1/2" hex head from Advance Auto. I have an extra one sitting right here and I just measured it. I've seen alot of people who say 1/4", so maybe our cars are different. Mine's a '90 IROC with the 350. I've been wondering where the 1/4" is coming from for some time, so if anyone can clear this up I'd be interested to know.
