I have a really old Ecklers exhaust valence panel that appears to have been poorly made and/or has been sitting for years with a large weight on it. So I have toe reshape the panel so that it fits.
Having a hard time seeing where it is bent and how it "should" fit.
Maybe a few pieces of aluminum angle judicially glued or glassed to bring it back to shape?
It is poorly made in the first place and hand trimmed. Then it looks like something flat and heavy was stacked on top of it for years. The other problem is it's really brittle and I suspect it would crack if you tried to force it into shape.
