The throttle stop has nothing to do with the grips. You hook the cables to the grip and adjust them.
If you look at the Ness grip part number for victory is the same for the Harley.
Rolland has no grip listing I found for victory.
Long as your so far away do this. Pull your grip and go to a Harley shop and compare then you will know for sure. It will not matter if its a new or used grip. Don't tell the Harley shop what your grip fits that way you will not get any bull shit.
You find out there the same ask what they would sell you the grips you want. You might save some money cause you will not pay shipping.
