As usual, I seem late to the party. I bought a '73 RS in 1986. It had been fully restored except for the obviously leaking heat exchangers. I bought a set of new SSI's from EASY at a nice price. When I installed them I realized the factory units were barely finger tight and otherwise fine. Still, the SSI's were a fitting upgrade. Many years later I met John at SSI when I ended up buying a basically brand new Ruf 5 speed from him. That turned into a long afternoon after realizing that his products very much reflected his person. What a shame. We have lost all of our great Porsche related businesses in this area.
