New engine motor mount (requires modification) for Datsun 240Z, 260Z, 280Z and 280ZX, 1970-83. Will work for right or left sides. All of the aftermarket motor mounts have the locating pin a little off of where it should be, so this pin will need to be cut or ground off for the mount to install correctly. The OEM motor mounts are the only ones we have found to have the correct pin location. Motor mounts can be installed one at a time by using a floor jack or an engine lift.
