Need help again

As most of yall know I am running the factory single master cylinder.
I would like to go to a dual master cylinder that will bolt up on my 66 Valiant
Do they have a dual master brake cylinder for my drum brakes ?
This is my next upgrade for Victoria that I was told I should do next.
I have spent an hour looking in the tec thread so I would not have to start a new thread. I am hopping I can use the original lines to the rear and add new lines to the front. Can this be dun ?

Thank you again tec's.
