| This is the rear cover gasket for the R200 Differential. Always be sure to double check the style of differential that you have in your z before ordering parts. For identifying by picture, which diff you have just go to Used Differentials and look at the pics for the 2 styles. There is the R180 and the R200. The R200 is the bigger of the two differentials. You may also be able to tell the difference by looking at the pic we have of this particular gasket that is posted with this listing and compare it to the gasket pic for the R180. If we happen to be out of stock please allow an extra week for delivery. Last Updated 12/11 |
