I am working on disassembling my 73 Maverick for restoration. Last night, I was finally able to fight the bolts off the front bumper mounts and get them off the car. I already knew the fender apron and battery tray were in need of replacement but I was a bit dismayed to find that the frame area that the bumper mount bolts to has rusted away as well. The damage is only on the passenger side. The driver side frame is in good condition. Aside from a couple small areas on the driver side floor pan, this is the only rusted area on the whole car. The cowl vents are even in very good shape. My question is, what is the advisable course of action? Is this repairable? If so, what's an acceptable method of repair? I think I've seen some pictures on the forum of these frame rails removed from cars. How are they removed/replaced?
