Help - Radio Mount Screws

[DanOh]

So I was riding my 2002 RSV home from work and pushed the up arrow on the radio to change the station. Instead of tuning in to the next station the radio stock flopped forward. The two screws that are supposed to hold it to the mount must have got lose from vibration and came out.

 

Does anyone know what size replacement screws I need? For now I've got the radio attached to the mount with tie wraps.

 

Thanks,

Dan
