flux conversion questions, motor plate

[jediguru]

I'm in the midst of a flux conversion and am trying to get my parts sorted out that I need. Looking at possibly getting the TCS chassis plates and hpi motor plate. However I have my doubts whether the hpi motor mount will work with my motor. I have a hobbyking 9XL. So, I'm looking at possibly getting this mount http://204.186.93.64/MotorMounts-Savage.html. Its the one at the top of the page. This mount is meant to be used on the holes in the engine plate where the nitro engine mount would normally attach to. My question is A. can the nitro motor plate be used with the flux chassis plates or B. is the hole spacing on the flux motor plate the same as the nitro motor plate. Hope this is clear enought to understand.
