I looked back and the first three people who responded were patronizing and insulting in their comments. One of them was you.Now heres a thing.
I have never said, I know how to, or its a stupid idea. But then I am not a novice mechanically. Many here are in the same boat, some even do it for a living.
I asked you for what car they were fitted, cos my documented eveidence doesnt match.Yes I have seen them for sale and they only seem to fit years 2010-2013, now they could well be the same passed that but that was when the L322 became L405 so it could well be the same.
When ever I try to find diff/driveshaft parts they seem to cut off at 2007/2009, then go 2010-2013, which tells me there is a high/med risk that they are not just a straight swap, Or other parts would be needed.
The best I can offer is you ask the guys selling if they could get you some good side by side pics of each year. But even then there is no garuantee they are the same internal fixings.
I was tring to learn a bit myself and maybe help you/somebody else in the future.
I am also now going to have to get My 2011 TDV8 8speed over my pit sometime and check this ratio thing first hand.
I will be checking front and back, but I cannot believe anybody is stupid enough to put a different ratio in only the rear.
So as many posters of threads on here maybe you didnt give the right info in your responces to the initial questions.
There will always be help from many members with experience here even if they dont know they will try to help work it out. Most accept that everyday can be a school day.
See the thing is we are now 2 days in and I dont see anything you have done to help yourself (on both threads you have running).
So if you want to continue just watching then thats up to you. If you want to fight everybody cos they didnt read your first post correctly then why put info in that is not relevant?

"This info is a little confusing kiddo."
You did not say that but that was the first response that I got, and it doesn't take a psychologist to understand that this is a patronizing condescending comment.
