Hi, I noticed that the FDR (Final drive ratio) is 3.692 for all 08 g35s. I have an AT on my car. Does that mean I can do a straight assembly swap my stock open diff to the stock VLSD from an AT car from my year? Can I do a straight assembly swap from a wrecked g35/g37 MT or will there be other parts I need?

Basically without doing whole rear diff rebuild what are my options in part swaps from an 08 AT sedan with an open diff?
