Both quarter panels had major rust and dents. Areas on the quarter panels had bondo nearly 3/4" thick. The edges around the wheel well openings were completely rusted away and previous repairs consisted of forming bondo to appear as though the metal was still there.
I started the repair by cutting the quarter panel enough to be able to remove the rear inner and outer wheel wells (see picture 3 below). Next I overlayed the new quarter on top of the old quarter panel and scribed the edge of the overlap. I removed the new quarter panel and marked a new line 3/4" inside the line I just scribed and cut the old quarter panel on that line. After fitting the new quarter panel on that 3/4" overlay metal and achieve a perfect fit I drilled holes and fasted the panel using clecos (see pic 5 below). Next I used a thin cutoff wheel and would cut about 6" at a time on the edge of the new panel, I was then able to push in the NEW quarter panel edge to be in alignment with the edge of the old quarter panel and place a spot weld about every 2 inches (see youtube fitzee.fabrication, cut and butt video to see how this works) I would repeat this process until I made it all the way around the quarter. Every time you cut the edge of the old quarter remember that you are leaving a 3/4" strip of (original quarter panel) sheetmetal that needs to be removed inside the car.
Previous driver side quarter panel repair used a lot of mud, wheel well and quarter going to be replaced
Passenger side is as bad as driver side, replacing this side as well.
removed enough metal from quarter panel to remove wheel well and replace with new.
I overlayed the new quarter panel onto the old panel and marked the old metal so I knew where to cut for a butt weld joint. for more details on this panel replacement process go to youtube and Fritzee fabrications, search "cut and butt" in his videos.
New quarter temporarily held on with clecos.
Spot welding is about done and ready to grind crowns off. Minimal warping from welding
Not pretty welds but I'm happy how it turned out.
lots of grinding left to do but I feel a ton of relief. I spent almost 2 months building the courage to do this work.
