My speedometer cable in my 61 Apache acts like it is very dry and needs to be lubed. Does anyone know if the center cable is removable and if so does it come out the top (speedometer) end or bottom? I have some speedo cable lube (yep they do make it) but I am not sure which way to pull the cable to lube it. I am trying to do it simply and do it cheaply (I'm already over "budget" on the truck). Thanks for any help you can give.
