Wynne,

Brake Booster from your 70' will work if your gonna change to the 71'-72' disks.

I have a 69' and I'm using the brake booster from it for the 71'-72' disk conversion (just did this conversion last weekend). I of course needed to change master cylinders and now use the proportional valve. Drum brakes use a smaller resiviour (sp) master cylinder and a distribution block. Note: brake line sizes are different also
