Hello! After years of wanting, I just got my first Land Cruiser: an '81 BJ42. I've already started restoring body parts and looking for mods, but I've noticed that the frame has a few rusty parts that I want to fix... My first instinct was to just replace the frame, but would it be safe to cut out the rusted frame parts and just weld in new steel? The main area I'm concerned about is the far back of the frame (basically where the license plate attaches). Any input would be greatly appreciated.
