The clutch reservoir I would just buy new and upgrade it now so if you ever plan to buy a good aftermarket clutch you have a good clutch master cylinder to support the extra pressure needed to disengage the HD clutch.They are right around the same price as brand new OEM ones anyway. You can also get upgraded Slave Cylinder too. This stuff also helps to keep your Synchros in better shape for highRPM Shifting allowing you to use a short throw shifter without damage to the transmission from shifting too early. Pedal assembly I'd go with whatever generation civic you have so an EG 5spd pedal assembly would probably be best. MY 2 Cent
