Where should I cut this body line?

[Sam_Fear]

On my F100, there is a body contour line that bumps out on the lower side of the bed and wraps around to the back. I need to move it "in" (so it doesn't bump out as far) about a 1/4" on the side, but the back will not be pushed "forward". Where should I make the cut/cuts so I can stitch it back together? Slightly above the ridge on the side? How about the corner? Also the bump out needs to taper to flat as it goes forward. Sure, I can't make it easy!

Any ideas or suggestions are welcome.

Picture for example - It's the lower bump out on the back corner:

Forget it, I figured it out. Just needed a break and a fresh perspective.

Good, all I got was a red X and a headache trying to figure out what you were talking about.
