When I force the back of the driver side to the top of the body stripe the door sill flange rubs on the underside of the door, so I'm guessing the stripe indent will need to be filled to look like it does in the Z1 pic.
Other than that I plan to use a couple sheet metal screws in the back wheel well, the stock screw in the front wheel well and a couple screws in the door sill flange to hold it in place.
