Detailed pic here: Dial up run away
I purchased these last week on Prime here: http://www.nsxprime.com/forums/showthread.php?t=50680
I had intended to install them in the coming weeks but another project has taken its place (I picked up a 6 speed tranny on eBay from Davis Acura!).
The price is $225 + shipping (recouping the cost of the parts + shipping). They will be shipped out within 24 hours of payment.
