I got a few other things going on under that left quarter panel. It had a big dent over the wheel arch, and the outer wheel house was pushed in, and the front edge of the wheel opening at the bottom was torn. How that happened over the years i dont know. When i did the first repairs i used a slide hammer with a hook to pull the arch out, at the front i made a new lower wheel opening corner, and just welded the wheel house edge without lip on it right to the backside of my repair. The trunk drop off on the back has a rust hole thats small enough that it can probably be repaired when the quarter is cut away. I will have to look at both of these pieces and decide weather or not to replace them when the quarter skin is off.
At that time while the panel is off i will also be fixing the broken quarter window rollers, greasing up the window tracks, and welding up the cracks around the door jamb striker pin, and reinforcing the door jamb with a doubler plate on the back side.
