can you buy these seperately from the whole kit ? and if so where

they're the exact same as the regular side skirts, only the HST ones are painted. The answer is no, not yet. I just sold mine, so unless you can find someone selling theirs goodluck. In January LR dealers will be able to sell individual unpainted HST parts . But if you're trying to get the side skits it would be pointles sinceyou already own a set on your vehicle.
