I got a 1989 jeep xj that I just aware out the ba10 fur an ax15.. I got a new clutch kit for a 89 jeep and now I can get the clutch pedal to build pressure till its half way to the floor.. and I can't get the clutch to release.. is the internal slave cylinder different between the ba10 and the ax15? I have a 91 ax15 so its not the external slave...
