The kit I got from NAPA had two seals and according to the diagram on the instructions,one of the old seals was installed upside down,and had a washer where it didn't belong too...was surprised it never leaked for 16 years that way!..
I still fear I'll be driving and the dam seal will start gushing far from home though..it was a rough trip home the first time it started gushing,I got about 3 miles before I had to pull over and refill the P/S pump,used almost a gallon of ATF to get home 10 miles from where it started leaking profusely..and with hydroboost brakes,you have practically no braking power once the fluid level drops and the P/S pump starts squealing like a stuck pig..truck steers like a Mack with seized king pins without power assist too..
