I have had to dolly that line so that it mirrors the OEM quarter. The panel never was intended to be a factory panel. So it is understood that the installer needs to have some ability to adjust as is needed.
The metal is soft enough that it is not hard to do.

Sorry it is all that there is out there for a repair of this area.

I had the almost the same problem when I replaced mine.
Had to make a cut on both sides of tailfines an hammer form the corner and weld in 5mm strip on the outer quarter to get the trims to align with the quarter panel.

These aftermarket panels are often not even close to what it should be and requires lots of work to fit.
If you have the old door jamb left and its in dissent condition weld it to the new panel or you will have to do almost the same as I had to do on the tail.

need to know how you guy's get a tight enough fit for butt welding ?.Do you over lay the new and old and cut with a abrasive wheel, or do you scribe lines and cut to match, then trim as needed ?

There's a video that was recently posted, showing how to do that....
Butt welding sheet metal the easy way. - YouTube

 

Do you over lay the new and old and cut with a abrasive wheel, or do you scribe lines and cut to match, then trim as needed ?

I have never had consistency with overlap and cut with an abrasive wheel. Maybe it works in some specific instances, but you will still have a gap the width of the abrasive wheel even if the cut is perfect (which it won't always be, especially when learning). I prefer to scribe and cut to match.

Getting a good line to line fit with no overlap and no gap can be difficult, and it's easy to make a mistake. One thing I do when I've cut too far and have a gap is this. Cut a piece of the same material thickness 3/4" to 1" wide and weld it to the edge that's been cut too far. Metal finish your weld. Then you can mark and trim again to get an acceptable fit.

Some things I saw in that video. First the guy was welding without a welding helmet. What the hell? Next he had a backing plate. Not every situation has access for that. Also it's very easy to weld to the backing plate - then how do you remove it? He had square corners on his panel. It would have been much better if the panel had a big radius on each corner. Last thing is I don't care how skilled he is, it's almost impossible to weld a panel like that and not have any warpage - which he showed he didn't have. He almost certainly got that straightness from working the weld area with a hammer and dolly as it was being metal finished. And that wasn't shown, implying you don't have to deal with that - and you do.

 

Good info in this thread, thanks for sharing
