I've tried to search repeatedly, but cannot locate anything describing how to switch out the pumpkin on my g35, what the sizing issues are, and above all that, what my current gearing is vs. what is available in the LS diffs.

Anyone have any input? I have a 2006 5at, and truely believe that finding a used diff off of ebay would be the greatest mod for ~$300 (for me at least).

Thoughts?
