Front power drums wheel cylinder

[Mesopic]

Hi
I own a 69 roadrunner with power drums, each front wheel currently has
one wheel cylinder located at the top. I wish to change this to duel front
wheel cylinders (one top and one bottom) Is there a car i can take the brakes from? Any information would help. No i am not interested in swapping to disc's
Thanks

Twin leading shoe conversion. Is what i meant.

Anyone got any idea if 56 coronet front brakes (drums) will go on a 67 coronet?

That's an awful lot of work and enginerring for a questionable at best gain.

What about self adjustment?

Sorry i meant a total contact brake conversion from a 57 desoto for the front.
I bought the bits today have to wait till they arrive seem to need a fair bit of engineering to fit but lots of people swear by total contact brakes, a lot of people also swear at and against them though. I was after twin leading shoe as it spreads the force around all of the drum, for better braking.
