The manual sway is pretty much straight forward.
You will need obviously the flywheel and clutch peices, the hydraulic components, and the clutch and brake pedal assembly, trans mount and crossmember, and driveshaft.
Installing the pedal assembly is the only hard part. Everything else is simple and straight forward.
Buying a manual car and swaping just the tranny (if originally a N/A) would be far easier, but the auto to manual swap is not that bad.
