Part # help please

Is it a two or for barrel ?
I would not trust a parts number guess,One trip is better than two.
Some breathers are taller then others.
Take the breather to your local auto parts store
and they will be glad to fit it.:rock:
when the top is on it should be tight and not rattle or move.
It will fit in the grove.
A good counter man will save you two trips and be glad to fit you up.

Napa has been good to me for 25 years. Hugheys. !!PlugO:)
