Hi, I've got a 66 convertable with stock disc/drum brakes. It has a stock power booster with the jam jar. I'd like to do the MC swap to a dual MC. Can anyone point me in the right direction on this swap please. I have read that I can use a 67 MC that will keep the rod length the same. But I don't have any information on how to plumb the lines from the MC to the proportion valve and then to the brakes. Any help would be appreciated,thanks.
