How can I fix this gap?

[scogin918]

I have a problem with how the quarter was put on by the last guy. When you close the trunk lid the gap between the lid and the quarter is way too big (about 3/4") on the driver's side. One idea the painter had was to weld some bar stock to the top of the quarter to help fill in the gap and then use filler to shape the rest. Nobody makes just the top of the quarter and I'm not buying a whole one just to take this little piece off. Can you cut the existing piece off and move it closer to the trunk lid and fill in the new gap with sheet metal or would it be better to make a new piece? This is the last hurdle before we dp-90 the car and move on to the front sheetmetal. The trunk lid is a real nice piece that I got from Rick's so I don't think I'll mess with anything on that side.
