Ok guys, trying to mate an AX-15 from a '96 XJ to a '90 XJ 4.0. As per write ups and answers from the internet and CC, I was told to get a pilot bushing from a '74 CJ with the 304 V8 5.0 as that would have the correct inner and outer diameters. Perhaps I don't quite understand the workings of a manual, but as far as I know the pilot bushing slides over the input shaft of the transmission and also, the bushing is supposed to fit inside the opening of the crankshaft. Correct? Well anyway, the bushings I got from RockAuto fit over the transmission input shaft but does not fit inside of the crankshaft... The part number I got is Dorman 690-042 and measures .756" ID x 1.056" OD (as stated on the box, actual measurements are .746" ID x 1.050" OD). Did RockAuto send me the wrong thing or is there else wrong?
