Do you cut a new groove in the IM shaft for the lock wire?

Nope, and totally un-necessary. The position of the groove and the diameter, tension and design of the internal wire lock were all developed to specifically park in the optimum position for bearing retention. The Dual Row bearing when properly fitted to the Single Row shaft requires exceptional force to remove, which can only be accomplished with the Faultless Tool which provides support at both the IMS flange and the bell house equally.

No machining necessary, this is a total in-car retrofit when utilizing the Faultless tool. Thats why its an entire retrofit system.
