It will only require the hole for the tab that keeps the pot from rotating to be just slightly elongated. The Alps pots pin is closer to the shaft than stock by a small amount, maybe 1/16 or 1/8". A small file can be used to elongate the existing hole or a hole can be drilled next to the existing hole. I believe that the actual mounting hole for the shaft is of appropriate size. Anyway, it's an easy task and with the new hole being inside rather than outside, the knob will still cover it.
