Clutch Cable Identification

I have a 2000 GT 5 speed. I am the 3rd owner and have had the car for almost 6 years. The clutch will not disengage so I started to check it out and find the plastic/rubber covering on the cable is split and going in one direction and the inter metal housing in the another direction. A little history about the car, is that one of the previous owner at one time did modifications to the car and than removed them. So before I order a new cable I want to make sure a Ford cable will fit. There is no firewall adjuster. What else should I look for?

Thanks,
Stan

Thanks, I will do that tomorrow. A few years ago when I was doing something I saw it and seem to remember a light silver colored quadrant.
