Ordered My Disc Brake Conversion Kit
Like Joe did, I got my lines and block from In Line Tube. They are correct for the 1966 Barracuda but when I did install them I had to force pull the lines up a little from the block to meet the duel master cylinder that I used to replaced the single one with, other than that they went right on. I am going to be gone for a while, but when I get back I will try to take a good picture of the lines and block set up and post them for you.
