Does anyone know the thread size and proper material I can use to plug the smog holes on my 83 Hurst/ Olds. Thanks for any info it's greatly appreciated. Mark
They have dedicated plugs for those but 1/4" pipe plugs work good too and you can get them at any hardware store. Brass is better, but it doesn't really matter.
