Help & knowledge needed

when i swapped from s/six to 318/4 speed in my 68 valiant i just added to clutch and brake pedals to the existing pedal box. you just remove the pivot pin and brake pedal (you'll be fitting new bushes from brewers right? so...) and swap in the longer pin with the manual pedals. but i'm all for an easy life so i like doing less work for the same result, lol.
neil.
