How do I upgrade a 66 C4 transmission to a 67 style?
Have a 1967 Mustang with a 289 V8. The c4 transmission that was put in when I bought the car is a 1966 style "Green Dot". I want to upgrade to a 1967 standard shift pattern C4 transmission. I have found that I can change the valve body to upgrade. But what about changing the shift pattern.
