67 drum brake master with the 67 -72 metering block will be as close to factory as you can get. It will look correct and work exactly the way it is supposed to work. I used this set up when I restored my 65 Barracuda back in the 1990's It's a bolt in job with no modification at all .You are only adding a metering block and an additional line to feed the rear brakes from the new master to that new metering block that gets bolter on to the frame rail where the old single block is now.
