Haha fair enough. The Volvo stuff does work amazingly well I agree. When Ben and I were doing my engine rebuild we initially tried to use the Victor Reinz equivalent just to install the brass vent on the angle gear (same mod that you and did to the rear diff) and it did absolutely nothing...I might as well have just put a dab of water on it. Then we used the Volvo stuff and case closed.
Oh and for the rear swaybar endlinks, I believe that Moog also makes them and sometimes Rockauto has those so that's a quality option.
