Can I add just a clutch pedal to auto pedals?

I'm converting my 1970 Dart Swinger from auto to manual. I will be rigging up a hydraulic clutch setup to use with the CD009 6 speed from a Nissan 350Z. Is it possible to just add the clutch pedal to my current assembly, or do you have to swap in the entire manual pedal assembly?

Does anyone have pictures of installing an aftermarket pedal assembly, like a Wilwood, into an A body? With how expensive the stock pedal assemblies are, I'm wondering if it would be worth putting the money towards aftermarket. I'm not worried about maintaining originality (Obviously! I'm installing a Nissan transmission).
