Well I wish that I had NOT made the call that I just did Quaife USA what a bunch of retards they are - buyer beware in big letters!
After having me UPS the oil pan and diff assembly to them three months ago and hearing dick from them since they now tell me that the units they have there are the wrong ones for my car and I’m S.O.L.
Strangely enough I just type in skyline of the Quaife UK site ( they are actually made there) and up pops at part #, it’s 8.12PM there at the moment so nothing until the morning. But you can bet your ass I will be informing them about how crap their US distributor is- grrr…
