starter won,t start

I have a 67 belverdere 318 all stock but has been changed to el. ign. It has started like a champ for years but today ,no.Lots of battery,radio works etc. but not even a click from the starter.Any help on where to look would be nice,trouble is I have the car wedged in a bad spot on a slope by the carport so will be hard to jack it up.I,m thinking the box { can,t remember what it,s called,by the steering].How can I test it
