Augy, At the PY site, check out part RFF17B - 67-69 SUPP TO FDR SCREW SET. See if that's what your looking for. I suspect they are philips and not Pozidrive. Both look very similar. For anyone wondering about the difference, here's a link I saved some time ago which has a description: http://www.justbrits.com/pozi/pozidriv.html
