Pilot bindings on rollerskis

I am about to order yet another pair of rollerskis. The company does
not have a Pilot rig so I will have to install the bindings myself.
Two questions:

1. Do you tap holes in the aluminum board and use bolts? Or do you use
Pilot stock screws and force them in sheet metal style, like you would
for snow skis, w/o tapping the holes? Do you use some sort of adhesive
to secure the screws? If I must tap the holes, can you recommend an
appropriate screw size/pitch? I have access to a fully equipped
metalworking machine shop with metric and inch taps.

2. Does anyone have used Pilot Equipe skating bindings for sale? Year
does not matter as long as they are functional (can be yellow/black/
gray). I figured I would ask before shelving out $99.00. No luck with
ebay. Contact me at runcyclexcskiNOSPAMPLEASE at gmail.
