Hello all, My 66 c20 has a very irritating noise coming from the speedo. It works but the noise is making me want to disconnect it. Im pretty sure it's in the speedometer, but I guess it could be a bad cable. Is there any way to check which it might be? Also, if it is in the gauge, how hard is it to pull the speedometer and check it out.
Thanks for any assistance you can offer.
