Your spa is square so all you should have to do is unscrew all the mounts be carefull if you have hydrolic shocks as the brakets will want to shoot down possibly scratching the spa skirt remove shocks if you can first this can be hard sometimes.
Spin the whole works to where you want it and reattach the mounts to the spa.
If you have a synthetic skirt you may want to predrill pilot holes for the screws
I have seen the synthetic material split before.
You can fill the old holes with silicone or wood putty if you can match the color,we have also put same or similar screws back in then covered with the little plastic caps that come with the lift. If you need some of those I have quite a few I would send you, same with the screws.
Good luck!!
