Tightening screws on Technics tone arm

Right off the bat; not the screws on the top and side of the tome arm pivot. If you look on the underside of the tone arm, where the shiny bit meets the brushed metal bit right by the tonearm rest there are 2 screws which are near on impossible to get to with a regular screw driver. Back home I had a screw driver that was bent at 1 end and could get in there nice and easy. I'm in a different country at the moment and so can't think of a way to tighten these screws. I'm assuming you have to pretty much take the pivot assembly apart to get to these screws? Anyone know of a way around this? I managed to source a set of technics for the bar I DJ at (at last!) and one tone arm is loose as a mother fucker at the point described above.

Any help appreciated.

Cheers
