Through the usual channels I was able to pick up a pretty cheap, used, JDM helical differential out of a type-r. What sort of parts am I going to need (if any) to dump the standard open differential, and install this one into my Y80 tranny (GS-R) transmission?

Little help anyone? Even a part number for the shimming kit would be a plus. The honda dealer here is worthless for info. They pretty much told me to go **** myself.

 

i'll ask at work tomorrow(david mcdavid acura)
