one other thing, I have a SPL diff bushing set from when I had my 350Z, never got around to installing it or even selling it. Kuah@SPL assured me that the front bushings would fit and the rear would stick out a little bit since the 350Z rear subframe is a little bit thicker. Last night, we checked it while we had the diff out. Everything looks good, I think I may end up keeping the diff bushings for my Z.
