Replying to Upgrading to pivot 18 toe piece from 14's to use CAST

What up everyone. I currently ride a pair of ON3P Kartel 96's with a pair of pivot 14's and I've been using daymakers to get some skin laps in while the lifts are shut down. Yesterday my daymakers tragically snapped (after only 4 rides) and I'm now looking into new options. Ive been looking into possible getting a cast tour system and if its a viable option I'm definitely going to make the switch.

First of all: do the pivot 18 toe piece have the same mount pattern as the pivot 14, because id prefer not to remount my skis.

and second... Would i be able to mount the cast tour base plate on kit on my pre existing drill holed from my pivot 14 toe.

I personally don't really know shit about mounting patterns but i would appreciate some help if anyone has some to give.
Thanks so much!
