i heard from my tranny guy thet the clutch cable is auto adjusting. just pull the clutch pedal towards u with your foot, until it clicks. and thats it. i replaced the clutch assembly on my 1990 sho and replaced the clutch cable as well. thats how i adjusted the cable.
There is a clutch cable adjuster on your clutch cable so follow your cable from your pedal thru your firewall until you see a threaded rod on your cable and tighten ( make shorter ) your cable until you have 1" play at the pedal
