I'm sure they'll figure out a good retrofit solution.I just installed my Squadbox 2 days ago and have discovered a major flaw. You can easily reach into the hole on the back left side that is for the hardtop connections and pull out the left top cover piece. I have contacted Tyler regarding this and he has told me they are working on a solution for that and it will be about 3 months before they have a resolution. I am not happy considering it cost over $700, I fought this thing for almost 6 hours trying to install due to the instructions being horrible, only to now discover that it is not as secure as I need it to be.
I have the Slipstream and it has hardware underneath that secures the top panel to the body side so it cannot be lifted off.
