don't think that's cut. mine needed to be cut shorter front & rear, front was with rotora lines not stock, but rear were stock & still needed to be cut a bit or it'll bottom in the caliper before compressing the compression washers... unless he sourced a shorter banjo? guess we'll see.
best advice is search around in a hardware store or whatever & try to pick up a nut that this bolt threads into, this way if/when it needs to be cut while installing you can do it, just thread the nut on just past the cut spot, then cut & file clean, then unthread the nut to repair the thread end cut, it also protects the threads above the cut & helps to get a square cut. should have this with you incase, I think you may need it...
