Reply to VCI Acade button Mod - DIY hole drilling?

Anyone know a cheap DIY way to make the holes though the VCI (i have the older style with the beefy steel).

These are the arcade buttons i have been looking at because the http://www.happcontrols.com has been down the last couple of days.(Atleast i cant access it anyway, i am getting 404- page not found errors). Also this place will probably wind up cheaper for me to order from.

Also will that locking mechanism stand up to what i need it for, or should i be looking for a screwing mechanism? Or will superglue keep it snug ?
