Stop in for a cup of coffee

Got lift, Sans manual. It is a MX 10AC bendpak lift. Cannot find diagram for bolt pattern on floor, it is not square, the posts sit on an angle. Looked at bendpak site, no joy......I get you drill holes after the posts are raised, BUT the top piece install needs the two posts to be close to the right angle to connect them...
