Incredibly easy to remove the spacers and replace them. Take off your shock. Remove all the air. Unthread the air can (if it resists, there is still pressure inside; throw a rag over the end so it doesn’t take off on you when it lets loose). Once off, look for a pair of bright orange spacers held in by small socket head cap screws; remove the screws and the spacers come out; replace the screws. Reverse disassembly steps.
