Hello everyone thanks for all the information. I am helping neighbor do a timing belt on 1987 D21 4x4 and RH camshaft seal was leaking and when we removed the sprocket we found the cam was busted around the dowel pin . Tried ordering one from a online dealer and they sent email back saying it was discontinued. When looking up the shaft on the dealers website it appeared that the cam must come from a production years of 11/85 to 07/87 this one was made in 10/86. I'm having trouble finding a RH one aftermarket also. Any help would be nice, VG30 TBI with only 115,000 miles and rust free body.
