Does anyone have the measurement size for the magnets on Diaclone drivers? My next door neighbor was cleaning out her basement and brought me a box of old toys including a Shogun Warriors Godzilla and a Kronoform Multi Force and Attakon. There were also a couple of drivers in the box but they are missing the magnets off their feet. I would like to get these guys set up with some new magnets and was wondering if anyone has the measurements.
