Tools required;
torx bits and driver, 10mm socket and driver, hook to pull c-clip, plastic spudger door trim removal tools, dremel grinder to remove mechanism pin, 2 pair of tweezers.
The suggested spring size is the same as a standard brush set spring for a AC wall powered grinder or drill motor, or brushes from and alternator brush set.
The spring we used was similar in size but not from a brush set, it was purchased at the most common Australian hardware store , who's name shall remane nameless because of the Kauri tree forests in WA they destroyed for lumber. If you are an Aussie you know who they are, and now you know how they got rich enough to buy out all the small hardware stores in the country. By wrecking old growth forest and turning it into lumber.
