My speedometer (I thought) wasnt working,while trying to look for the turn signal relay I found my speedo cable not connected behind the gauge cluster,so I temporarily got side tracked to the speedo cause I was dying to know if it was going to cost me an arm and a leg to fix it,long story short,speedo works,cable is good,but Im guessing I need to replace the gear in the T case,can anybody tell me how to remove it for replacement? ( and I found the relay,it went bad,but I guess its 40 years old,
