Adjustment tool for TPS screw

I just replaced TPS sensor on 85 Caprice 305 w/ 4bbl quadrajet. Old sensor was broken. After replacing, the check engine light came on and one possibility of code was TPS out of range. I checked voltage and it was out of range. So - I try to adjust it and the screw doesn't have a slotted head - it's a little hex head around 2mm and I can't find a tool small enough to get in there. I've looked all over, Sears, Autozone, etc. and can't find something to adjust it. I bought a carb rebuild kit thinking maybe there would be a little tool in it - no luck. I assume I could buy special tool at dealer.. but I'd like to find one somewhere else! Anyone know where to get the adjustment tool?
