Those are the areas you need to check as the pics show. I also have pics in my Christine Build Thread, but not sure what page it's on.

If it's just some rust and no gaping holes, you should be able to maintain it, but if the area is rotted away, then you may want to find a welder that can help you at a reasonable price or find a better one.

Mine had burnt exhaust valves when I purchased it at 130,000 miles. I only rebuilt the top end and no issues so far.
