I have found a source for the 4kq center driveshaft u-joint... Try calling Driveline Service in Portland, OR. (503) 289-2264. They have a joint made by GWB of Germany. P/N 287000600000. It is an exact fit AND it has the grease fitting on it. Price is a bit steep at $51 but it is an exact OE match. -Peter '86 4kq
