If your car has a stock cable, stock quadrant, and no firewall adjuster but feels like the pedal is to low the cable has probably stretched some. Depending on how much the cable has stretched you can most likely remedy your problem by installing either an adjustable cable or a firewall adjuster. If it were me I would do both along with a quadrant. The stock cables and quadrants are known to go when "performance" clutch kits are installed. As far as I know you can not adjust the cable/pedal if everything on your car is factory.
