that’s the right one, the BBT-5 fits those older Shimano 12 spline cartridge BBs perfectly. Just make sure you remember which side is left and right when you reinstall, those threads are backwards on the drive side and it bites everyone once. Also worth picking up the BBT-9 if you ever upgrade to a newer Hollowtech II crank, you’ll need it eventually.
