Golden Greek and the iSeason

[Xylocaine]

I was curious if anyone has the measurements on the various parts for the GGTS and the iSeason and if they are interchangeable at all? Primarily interested in the negative post spring size versus the iSeason's native threads though also interested in button replacement. All help super appreciated

Also interested in knowing what size magnets would be needed to replace the iSeason's spring switch.
