I have used Yaesu rotators with Rohn and Universal towers and I do not
recall having to drill the plates. It is interesting that US towers cannot
accommodate Yaesu rotators without modification.  I think one of my
rotator plates just had elongated holes so it may be possible to use a
Dremel or file to modify the US Tower plate.

I recommend a drill.
