I don't see a problem squeezing in the SPL bushing if you have not done what I had done already... it will compress slightly to fit in (unlike solid aluminum).

So if I read this thread correctly, if I wanted to just to replace my old bushing and install a new urethane Whiteline bushing in my 370z, I am still going to have problems with 1) removing the old bushing and 2) installing the Whiteline one since it is for a 350z (like the SPL version)? Is that correct? From what I can tell no matter what, I will need to shave the subframe right?

Removing the old bushing will be a pain.
The Whiteline should slide right in.

Just an FYI - I talked to Sean at SPL Parts and they do indeed have all the new bushings needed for the 370Z diff. No shaving needed for the install of their parts. They just don't advertise very well I guess since some of you have gone through a lot of bull sh*& to get the sub-frame bushing out and buying other 3rd party 350Z parts to make all this work. I will be buying the kit later this week for my diff seal rebuild. What the heck - the diff is going to be dropped no matter how you slice it to replace my "breathing" oil leak issues on the side seals so I might as well replace all the OEM bushings that are going to wear out sooner rather than later - to hell with the noise. Give me track time.

My next question is does anyone know the fastest/easiest way to get that bad boy bushing out of the sub-frame? Seems that is the hardest one for replacement.
