Help: Knob grips

The rubber grips on the volume/tone/piezo knobs on my 2004 JP6 are starting to break. I bough a replacement a couple of years ago from Strings & Things – the UK distributer – but it was smaller than the original & broke when trying to fit it.
The Ernie Ball UK website has either chrome or black ‘Tele style’ knobs. Anyone know if they’ll fit on my (now old) JP6?
