1958 minx hand brake cable from scratch

hello, currently i have a 58 hillman minx but no brakes at all and didn’t have the hand brake cable either when i brought it. what are some products i could use to create a cable and the end points. i do have the handle and the end the cable connects to just cable is missing and cant find replacement and have no clue where it would even run under the car if i got a proper replacement.

Then ill go to checking and maybe rebuilding the brake master cylinder or replacing it who knows at this point.

but drives like a T bird as some may say
