That one looks like it may have the same rust issues that you have. He claims that it has a solid body and the appearance looks fair.
They all "look" solid but when you take the fenders off you find out just how solid they are!!
Nice job Ned. Looking good. The rust pics remind me of what I when I started. Especially the left cowl. Look in my photobucket and you will see what I mean. Other places you mentioned were bad on mine as well.
Keep the pictures coming.
