Replying to QUICK! Technical mounting question/Lizzy question

I have a pair of Line Elizabeths, I was gonna slap some inserts in them today, and I noticed the 9.5mm bitstop puts the bit REALLY close to all the way through the ski. Then I measured the existing mount hole depth, and it isn't anywhere near 9.5mm (they were mounted at a shop). Is there a special depth that Line Elizabeths are supposed to be at? Cuz its news to me, and I don't want to mess them up.
