Jeep clutch fluid question , 1988 Comanche 4.0 6ci.

I just got this Jeep I was told the clutch was just replaced , I can see the master cylinder is new , the fluid was dirty so I drained it out and replaced it I was told that Dot 3 brake fluid was fine by the NAPA guy, now my clutch works but makes a "rattling sound" when fully engaged , tried bleeding off the system , the 2 lines that come out of the Bell-housing are not secure must be a part missing that holds them the line with the bleeder valve can be pushed in and out , need schematic to see if part is missing, any help will be greatly appreciated snipped-for-privacy@usa.com Curt
