I did it in the dark, on the freezing concrete floor, in our small garage, on all four wheels of the 83, with the tires on, worked fine, but was NOT a pleasant experience (very cramped and cold). I didn't spill a single drop, using the power bleeder + tubing from the bleeder screws to the container I had worked great.
