I share a problem that seems to be very common for 30+ year old e-bodies. My speedo grinds above 40m/h and the needle shakes irratically -the cause of this being rusting speedo gears. (I'll also replace the cable) Has anyone restored a non-ralley dash themselves? I would like to sand/oil those gears. Is it possible to get into the gears? Also, can the clear plastic be removed from the front, lending itself to a good buffing?
cheers
