MikeB, What lift is that you have? I have 11"6 ceiling and have been looking for a 2 or 4 post lift with the short posts for clearances. Assuming that your lift is at least 9k#. Do you happen to know the depth of the floor you have that on? One of the problems I have run into is I'm on a residential floor, only 4.5 in. thick. Many heavier capacity lifts call for 6" minimums.
