gotta replace the odo gears, can't get the speedo needle off. what do I do now? the instructions I have say 'if there is any resistant (when removing the speedo needle) we suggest you stop (using the fork on the needle) and remove the reset assembly by unclipping from back side of the unit and remove it... ----- what does that mean, how do I do this, do I pry somewhere, do I bind something?....this is such intricate diamond cuttiinglike work.... maybe I should send it off for a pro to do it.
