the t5 and t56 slave cylinders both use a quick connect fitting for the factory hydraulic line. I'm not using the factory line, but I was able to find an adapter fitting that goes to a -3AN line, same size as my Wilwood master cylinder. It was not a cheap fitting though.
another thing I came across, t56 slave cylinders have no bleeder valve, t5 slaves do. so I went with the t5 slave, it was cheaper too!
