Picking the right clutch for my Duster

Getting my winter project started and will be replacing my clutch and doing some transmission work. I have been doing some research on a clutch and I'm undecided so far. Do all diaphragm type pressure plates require removal of the clutch spring at the pedal assembly? Car is a 70 Duster 340. Hays, Zoom, Mcleod, Centerforce, RAM?......To many choices but I would rather keep the spring.
