After cranking up truck, the clutch dropped all the way to the floor and wouldnt come back up unless i picked it up. after looking under hood. i noticed the cable going into truck dash was not attached. after looking under dash i found that the end of the cable was broken. do i need to replace just the whole cable or do you think there could be more work to be done. is replacing the cable something I could do myself? what other adjustments will need to be made after installing cable?
