Exhaust manifold A.I.R. tube help---

Working on my LT1 swap to '64 Impala SS and may have to use the stock 94-95 style exhaust manifolds and want to plug the A.I.R. holes. Anyone know what size and thread plug fits the stock holes?

Thanks,

Seems like either 21m or 23mm. Been a while.

Thanks wrd1972. They looked like metric. Remember where you were able to find metric plugs?

It's actually a 22mm plug. I bought mine from NAPA (M22 Oil Drain Plug.)
