Help on upgrading brakes

I was hoping someone could help me out on a route for upgrading my brakes.
I have a 1971 dart with sbp and
Cragar as 14" on it and 9" drums.
I want to upgrade to disc brakes in front and still use my wheels and bolt pattern.
What would be the route to go ove searched all over but never got a direct answer
The direct answer is to find a doner A-body that has disc brakes. They will be Kelsey Hayes four piston.
They are out there. Just the core charge for the calipers was160 bucks last time I checked.
