I am trying to figure out how to install the zincs on my Alpha 1 Gen 2 trim cylinders. I have done all the rest. The trim cylinders however do not have any threaded holes to attach the zincs to. There are pockets that line up with the anode mounting holes and the pockets are oversized for the anodes screws. Do I need to drill and tap a pair of holes in each cylinder? If so how much room do I have to drill into the cylinder before I crack into the hydraulic chamber? Is there some other mounting method that I am missing?
