Tyrolia Jig Extensions

I am now the proud owner of a Tyrolia 92 jig (older skinny version). Works fine and dandy on my race skis, but I now need to drill a pair of fatties.

Tyrolia says the jig can go to 100 something with "extensions". Anyone know how do these "extensions" work? Can I ghetto rig my jig to mount a pair of 95mm waist skis in a similar way?

The extensions are a Tyrolia accessory that attaches to the feet of the jig. Basically looks like a down out down football pattern (an L with an extraline down) and gives you extra distance on the feet.
