Just for people that are reading this and getting confused over which kit this is, as there's plenty of different names being throw in. It's Equinox.
The side panels have a 2 inch return which you can trim so it perfectly matches your top rails. It also allows a bit more leverage to get side panels on, if tight.
When I fitted mine they had to fit over the chassis, floor sheet (2mm Ali) and quite largish rivets. They were fairly tight but went on fine without cutting lips off
