18 The passenger-side quarter-panel comes off just like on the driver's side. Again you can check the trunk drop off and inner wheel well. In our case the drop off was trashed, but surprisingly the inner wheelhouse was in perfect shape. We were sure that given the sorry state of the quarter the wheelhouse would be toast, so we had a Goodmark replacement (PN 4021-675-70R or L, $59.95 each) ready to go. It looks like the replacement panel would have been a good fit, but we were happy to save the five hours of labor it would have taken to replace each one, not to mention the cost of the parts.
