Part #: 800-249
New rear differential cover gasket for R180 rear differential. The R180 rearend was found in most of the 1970-78 Datsun 240Z, Datsun 260Z and Datsun 280Z's 1970-78. 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. * R180 requires 1 liter of fluid capacity.
