Xtx to backcoutry

[Stone9]

I am switching out my ripsaw for a backcountry. I see people have ran the stock drivers as well as extroverts. After research I am going with extroverts but still have a few questions.
When I press the extroverts on my shaft what dimension do they run from the end.
Do I need to modify the rails to make room?
Thank you all

I bought my sled setup with a backcountury track and extrovert drivers. I don't know the specifics but I know the front of my rails are modified and that I have to trim my hyfax to fit correctly. I can tell you that you are making the right call with the extrovert drivers, can run the track nice and loose without ratcheting.

Anyone have a picture to show the extros clearance of the rails??

Here's a video showing how this guy did it. You need to get the extroverts to run dead in the middle of where the old drivers were running between the lugs. Measure, measure, then measure again and double check like he does by putting the shaft in the track to make sure its aligned.
