I'm helping my friend do a clutch on his 91 Cherokee 4L. Its an internal slave and the old one has the standard hardline fitting that you use a flare nut wrench on. The new slave that came with the clutch kit has this black fitting screwed onto the hard line and has a clip on it. Do the cherokees have two styles of hydraulic line? I'm not really seeing how this is supposed to connect to the standard hard line and just seems kinda hokey to me. Thanks in advance.
