Alrighty, got my Bravo anodes in the mail last week, and since the temperature outside is only -6 C, it's time to get those power trim cylinders fitted....but wait...

, there's no flippin' threads in any of the four holes in the cylinder top cap! And the holes are too big to tap two for the stainless bolts provided with the anode kit.
I guess there have never been anodes on these trims

...which is why they're so badly pitted. Can anyone give me some advice? - it looks like drilling (and tapping) the top cap in between two of the existing holes is "the" way to mount trim cylinder anodes?
Thanks...
