my 5spd swap is complete except for the driveshaft. the 87-92 mk3 front half was purchase like i needed to get. but when installed only one bolt on the spindel went in whil the other did not line up. to short between the the two bolt holes. the other question is the harness. mine on the 2jzgte wont work, so i was told if i buy a 2jzgte harness from toyota an us spec it will plug in and get an ignitor also and im ready to go and start my car is this also true? thanks for the help at all of you at CL.
