I am the new owner of a RHD, 1967 Series IIA. I would like to do two things with the brakes;

1. Convert the brake system to a dual circuit
2. Add front disk brakes.

I would like to avoid having to cut the top of the wing and I do not want to convert to late 2A/III wings; I am okay with cutting the inter wing.
I have read Terri Ann's site but I still have some questions.

1. Does the Series Servo 6" require cutting the top of the wing?

2. Does the SantanaServo 8" require cutting the top of the wing?

3. Where can I find a Series III brake pedal box?
