I'm aware it's not a sedan.
I've seen at least one really good installer make a stepped ring on a router, which uses the OEM bolt holes, but doesn't locate the driver frame against the door. It moves the driver frame forwards, into the grille cavity. This allows retention of the mechanical mounting system, while gaining the space needed.
So, no, using the OEM bolts does not necessarily mean that the driver hits the window. Using them as if it was a sedan, I'm sure they do hit the window.
I'm looking for the pic I was sent, to illustrate more clearly what I mean.
