63. Dart with a hydraulic clutch set up?

62-66 A-BODY-MOPAR CLUTCH PEDAL KIT – Hydraulic Master Cylinder Clutch Pedal Kit (Billet Reservoir) - MalWood USA.

Probably not the least expensive route but what I believe to be the easiest. I have these in a 72 A-Body and a 69 B body. Very pleased with both applications.
