mine is a 2006 but just spoke to kevin at birds and he has answered all my questions

2007 on is a 13n which is a smaller quaiffe diff
2006 is a 10 n quaiffe diff

later cars have crowned not welded diffs - this is not the case for automatics

i have to wait for the guy to get back to me with all the info for the diff

thanks steve
