R180 Rear Differential Cover Gasket OEM 240Z 260Z 280Z

New Genuine Nissan rear differential cover gasket for Nissan R180 rear differential. The R180 rearend was fund in most of the 1970-78 Datsun 240Z, Datsun 260Z, and Datsun 280Z's. Over the years, some cars have been changed out to the stronger R200 rear differential. The R200 takes a different gasket, so be sure to check which differential you have. The bolt spacing and shape is different from the R180 to R200. *See PT# 800-249 for aftermarket gasket.
