Gary,
Being half a bubble off level isnt too bad. Did you turn the plane around the opposite way and use the bubble level again to make sure the floor doesnt have a subtle tilt? Your strong crosswind landings and takeoffs wont be normal for Coupes but they may not get into the dangerous range as long as everything stays optimal. You also quantify it by measuring the tail at 73 inches. Compare that to normal of 75 for a single fork nose gear and about 76½ for a double fork nose gear. So, you are somewhere around 2 to 3.5 tail low. Personally, Id download the instructions from Skyports website (down at the bottom of the page) and follow those instructions to calculate the correct shim thickness, get some and install them. That way, as the donuts compress, the air in the tires gets below optimum pressure or anything else happens, you wont be sagging into the too-high-angle-of-attack range that can cause problems.
