That weld in "patch" curvature in the photo looks like it has w-a-a-a-y too much curvature for that fender, Randy. It almost looks like you will have to disassemble the assembly, including cutting the cover loose, straightening it some and use the innards and relegate the the outer skin to the spare parts pile - about what you said. It looks like everything is spot welded together so you can pull it apart fairly easily - but - do you also have tire clearance with that extra metal hanging inside. Hagan used to make an angled filler pipe and a lesser curved version that probably would have fit better. I haven't heard much about them lately tho their web site is still active(http://www.haganauto.com/category_s/41.htm). Why go to all that work if you can get a better fitting version and Ebay........
