Sorry if this has been dealt with before... The bottom of the rear of the passenger front fender is not running parallel to the side of the car. The front edge of it- nearest the tire, is toed in over an inch. My apologies for not posting photos- I don't know how from this iPhone.
So. To try and explain better: if you sight along the right ground effects from the rear of the car, the front end of the ground effects turns in toward the center of the car, right by the Z28 badge, because the fender it is attached to does likewise. The whole bottom of the fender doesn't tuck under further, it is as is someone has twisted it or pushed the front part in further...
Where the fender bolts to the pinch rail underneath seems ok- does anyone have experience with this problem and its solution?

 

Take a picture, upload it somewhere (even facebook works, they dont even have to be your friend if you get the URL to the actual photo) then link to it.

 

Ok. I will do that in the morning. To try and explain it more clearly in the meantime- imagine you are sitting on the ground on the passenger side of your car, facing the badge below the door hinge, right behind the wheel well. Reach out with both hands and grasp the bottom of the fender/ground effects, right beneath the badge. Now, holding tight with your left hand, push in with your right hand as if you are trying to push the fender toward the engine, until that part of the fender and ground effect is about an inch further in than on the other side of the car. Make sense?

 

Typical mis-jacking damage. The rear of the fender bolts to the pinch seam. When it gets jacked up there, pich gets bent and moved the fender out of alignment. Lots of pics here if you search.

 

As that part of the fender can twist rather easily I would look at everything including the wheel well inner liner for any bending and make sure the pinch weld bolt is square and properly lined up with the body. Make sure the whole length of the pinch weld is straight.

 

Thanks guys- I am aware of the jacking issues and thought the pinch weld looked straight enough, so I though someone might have seen this twisting before. I will jack it up again and spend some time on it...
