LK uses Lucas Power Steering Stop Leak

i have a 1991 toyota land cruiser with 138,345 miles on it and the power steering box had a leak,dripping on the frame collecting dirt etc... if you know land cruisers, parts are few and far between and expensive, so i debated to purchase a new steering box, then saw your power steering stop leak and gave it a try WOW!! no leaks at the steering box, saved a hand full of money and the steering is smoother . thanks
