Tail Panel Tune-up 67 Camaro

[SlowProgress]

Hello Metal workers

The lower tail panel is pretty beat on my 67 Camaro. I know the aftermarket ones fit poorly but I want to cut and use only the lower half to straighten out where the back up lights fit. It is very wavy from previous repairs and some burn throughs around the license plate opening from spot welds. I was planning to cut about half way up just below the row of heavy spot welds. Seems like I saw someone do this recently, but can't find the thread. Also searched "tail panel" with no luck. Anyone out there done this and posted some photos recently, or can supply a link?

Thanks,

Scott
