Scrambler Harrison Billet Calipers

Been looking at getiing one, but they advise only the thruxton comes close to fitting my 2017 S/Scrambler 900. Was wondering if anyone has or had experience with them on fitments. My disc is 310, and thruxton 320, so that was/is a bit of thinking in my part as to pad position. I dont want to go the free spirit route as i already have replaced the disc with a floating one, but looking for a better caliper. With some searching, some threads ive found have mentioned some off honda's but no photos or which definitive bike to go for, for a straight fitment. I know brembo ones have been done but finding a new one with the bracket, in this country anyway, is hard to come by, and dont fancy paying over the odds on import.
