Welcome. The car looks badass. Reminds me of my first fox stang only a little cleaner and better looking than mine.

Yeah you gotta get rid of that c4 if you want any kind of mileage. Check out the junkyards. You can find T-5's all day long and just get a pedal assembly out of a 5 speed car and your good to go. Get a clutch cable from Ford though. The aftermarket autozone specials last about 3 months.
