got these fox forks today and to look at they look new , but when trying to adjust the rebound the cap/knob just keeps turning , took the cap/knob off and noticed the shaft the cap/knob sits on is snapped .
whats best way to fix this ?
is it complete damper replacement or can the rod be changed ?

thanks
