280zx rear diff mount direction

Posted May 1, 20222 yr

Which way does the rear diff mount install in a 280zx? Looks like there is 2 ways it can be done, the right way or upside down.

Depends on R180 or R200. The right way for one is the upside down way for the other. I think. Vague memory...

I have a R200. The service manual says there is an 'U' marking that faces up but I can't find it on the new OEM part. New part has the middle vertical part offset to either the top or bottom depending on how you install it. Old worn part has the middle vertical part centered

My mistake. Looks like there are actually two slightly different mounts for the R180 or R200. Weird. Even weirder that the part with an "up" side is symmetrical. And the unmarked part is asymmetrical. I'd set the new mount up so that the two stud holes are the same distance from the car body.
