Anybody have any experience with working on/restoring older FJ's. Most of the threads I've read about involve '70's or newer vehicles. I'm thinking of buying an all original '64. The seller said that the older FJ's were made of thicker gauge steel and therefore don't have as many rust issues. Is this correct? Also, how difficult is it to lacate parts including sheet metal? The body does has a small amount of rot and I'm leery of getting an older FJ. Is rust a big problem with these vehicles?
