Datsun L16 1600 twin DCOE inlet manifold

[old_datto_fan]

I have a twin side draught inlet manifold for sale on TradeMe that I thought I bought as a Toyota 4AGE manifold - I only wanted the carbs on it so didn't care about the manifold.

Apparently, what I have could be an L16 or L18 manifold - can anyone give me some dimensions of the distances between the ports and studs on the head side of the manifold so that I can check what it is.
