All the Triumphs back in the day were pretty modular, so the parts should be the same except for length. You can probably use cables from a Sprint, Trident, Trophy, or a Tiger of any year up until 1998 or so. These all have higher risers or bars
Note that your 95 Speed Triple has a hydraulic clutch, so it won't be a cable. You may need a longer hydraulic line for that as well.
