I have just changed the oil on my fox float FIT RL's and i squashed the bit of metal the rebound knob screws onto. Is there anyway i can buy a new one and replace it? - Also although i oiled them (green Fox 10wt) they still 'pop' up a little at the bottom. Could this be the FIT technology? I have used normal Float RL's and they seem more plush.. any reason why?
