Does anyone know the outer or the inner diameter of the primaries and the secondaries for a Raceland 4-2-1 manifold for AFH/AFK? Or do you have one at your disposal to measure it? I would very much appreciate it!! I want to build a replica from stainless for an AUB in a newer Polo and the maths gave me some dimensions and i would very much like to compare those with a genuine Raceland. I would buy a Raceland but I live in an aera where the shipping costs almost as much as the mani and in this case it's easier and cheaper for me to build one. Thanks in advance!
