"platform" is not what you are implying it is. Sure, a screw or rivet might work to keep the rail from pulling off the roof. That's not the same as support for the weight. The Gen 1 roof is very flexible.Thx for all input,
I though roof symetry was same with the cruze since they share the same platform.
Anchor point could be installed, i remember once upon a time i did install a thule fit kit for my old 1993 eurovan metal roof. There is a tool like a rivet that expand. It can also be used on fiberglass roof (i also have a 1973 westfalia).
I can dig up to get what was the fit kit.
