You can use 30mm Sanwas. You can either ditch the PCB inside of drill the holes bigger then bend the button pins a little closer together to fit through the holes.

Here's a pic inside. These are the 4 spots you need to desolder. Once you desolder them then drill the holes bigger with the 1/8" bit or unibit if you have one.
Push the tabs in on the old buttons and push them out and then put the new ones in and line them up straight so they go into the solder holes.
