A few years back, ... ...the internal cavity cross sectional area & it basicly converted to just less than a 7/16 diameter.
Interesting. If the cast cavity had a cross section of just one AN-12 line, I would be happy. But not 7/16" dia (hydraulic). Any chance you can get those dimensions? For 7/16, I am thinking the height would have to be less than 3/16"
