Freeze-out plugs for manifold

Had to knock these freeze out plugs for obvious reasons. Can't seem to find 1" plugs on the moyer marine website. Anyone have any idea where to source these puppies?

I agree with Neil. Call Ken and you won't regret it.
Added wisdom and support at no extra charge.

But, for the record, it is in the website's ONLINE CATALOG under OVERHAUL PARTS - BLOCK

Oh yeah, and it's ⅞"

No it's not 7/8". Can't you see the caliper read out?

I can also see one of the caliper ears (left one in your picture) is well outside the hole.
For comparison, I just measured the same hole on my spare engine and it measures 0.948", filled with a brass plug sourced from Moyer.

Please call Ken in parts. He will get you what you need or advise you where to find it even if it means using rubber expando plugs from an auto parts store.

The Universal manifold you pictured requires Welch rather than cup style core plugs. Cup style is for a smooth bore hole and its plug is a tight friction fit. Welch plugs are for a core hole with a limiting shelf (visible in the picture), are a looser fit with the convex side out and then are struck with a ball peen hammer to expand/set them in place. An installed Welch plug typically has a dimple in its center from the striking operation.
