Part #: 200-598
New OEM Genuine Nissan rear differntial pinion oil seal fro R180 and R160 rear. This seal will fit most Datsun 240Z, 260Z, and 280Z, 1970-78. Some of the Z cars had the R200 differential or have been upgraded to the R200, so it will require a different seal. The quickest way to tell the difference in an R180 and an R200 is to look at the rear cover bolt pattern. Take a look at our rear cover gaskets to see the difference.
