How do you adjust a clutch pedal height on a 1971 Plymouth duster 340 4 speed car?

Inspect the condition of clutch pedal rubber stop, if damaged or missing install a new one. Where necessary, disconnect interlock clutch rod at transmission end. Adjust clutch linkage by turning self-locking adjustment nut to provide 5/32" free movement at outer end of clutch fork. This adjustment will provide the required one inch free play at the pedal. Reassemble interlock rod if used.
