OK so I minus well look into the Brakes.
1- Can I install a 1967 dual (two lines in) master cylinder on my 1966. Do they have separate systems for the front and back?
2- There is another rear drum braking system from a 1969 type 3, I believe (correct me if I am wrong, very likely) The have a wider shoe and provide more breaking power. I understand that They can be intalled Back Plate,and all hardware without any modification.
3- what is the story with front disks? I understand that they are very expensive.
