My donor is a 1989 XJ w/4.0L and AX-15. I am converting an 88 XJ w/AW4 to the AX-15.
I installed the aluminum spacer plate (between the 4.0L and the AX-15), the AX-15, NP242, AX-15 mounting bracket and AX-15 isolator yesterday. All AX-15 components are factory original and were transferred from the 89 XJ Laredo donor. My 88 XJ Limited was built with the NP242 so I installed it on the back of the AX-15. The engine/clutch cover bolts have been torqued so the AX-15 is tight to the 4.0L.
When I attempted to install the 89 XJ AX-15 cross member I discovered the mounting holes for the AX-15 isolator are correct considering left/right alignment but are too far forward in the fore/aft direction. If the cross member could be mounted further toward the rear of the XJ I would be okay. However, the additional set of mounting holes for the cross member move it further forward.
I also converted from the internal slave to the external slave cylinder but I do not see a difference in the clutch covers for these two types of slave cylinders. Both appear to measure 7 3/8" tall.
I estimate the misalignment between the AX-15 isolator studs and the cross member holes that accommodate them to be 3/8" - 1/2".
Can anyone explain or verify my observations?
Thanks,
Rick
