Mike,
Boy were you fortunate. I have the same thing Double Ugly has and would never get rid of them. They are great for any car and I can sit up under mine. I can pull the transmission in 20 minutes with no problem. I took my tank out once with the car on them and it took about 15 minutes. I just put a wide board on a floor jack to support the weight and then undid the straps holding it and lowered it slowly to the floor. I love the Kwik Lift as I can put it at any width for different width cars.
