I need some help on the next step of my repairs which is to possibly replace the outer wheel house. I fixed most of the rusted spots on the original. The spot that is troubling is lower leading edge that is connected to the rocker. The steel has some pitting. I purchased a replacement and I am on the fence to replace the whole thing. If I do decide to replace it, how is the best way to remove it? I see that it is sandwiched between the inner and some bracing. Would it be easier to drill out the spot welds with a drill bit instead of spot weld remover?
