I completed my led conversion last year then realised recently my speedo was out by about 5 mph.Anyway to cut a long story short when I reset the needle I moved it clockwise and now the speedo doesn't work at all. The question is can I just replace the white plastic speedo mechanism which you push the needle onto (which isn't soldered it just clips on) or have I got to replace the whole clocks? any pointers will be appreciated.
