For those who are planning on using OE clutch master, here are the parts i used: Clutch hydraulic line : 515 - 13930 ( AN4 ) . Speedway Motors ; FRA - 650222 ( adapter to Nissan line . AN4 to female 10mm x 1.0 inverted flare ) . Summit Racing . There are many different lengths on clutch line to choose from. The adapter goes where the original slave cylinder hose goes. You can opt to get an adapter goes straight to the master and different length line. I opted to keep OE hard line, this helps cooling the fluid.
