I am really confused now that I have read the transmission sticky and then ran across this thread:

http://thefactoryfiveforum.com/showt...-The-Race-Line

The Quaife web site lists the QDH3Y as having female output like my 2007 5sp transmission and shows it is applicable for all non-STI trans:

All the other info I have found (and listed at other vendors) indicate I should order the QDH1Y which has male output shafts (again, my trans has female ends) and use earlier axles with female joints. The Quaife web site above indicates I should order the QDH3Y which does have female ends. Will the QDH3Y fit the 2007 5 speed is the question.

The reason for all this rambling is i have found several new Quaife QDH3Y diffs available for under $700 delivered, quite a discount from the ~ $1,200 or so for the QDH1Y plus a change of axles.

I am probably opening all kinds of discussion again even though this issue probably been thought to be closed and answered! I will appreciate any input and will go hide again until the next crisis!
