Cylinder spigot question (Ambo/V7)

[Chuck in Indiana]

A friend that doesn't post here asked this question. I'm sure some here know.
TIA
Does anyone know if the spigot outer diameter of a Ambo cylinder is the same as a V7 Sport?

I have a set of Ambo cylinders I want to get nikasil plated to fit a set of NOS V7 Sport pistons I have laying around, but I want to make sure everything beside the bore diameter is the same and they'll fit a V7 Sport block.

In my experience, they're the same.

Thanks, Charlie.. I passed it along.
