Dean,
A wire brush and elbow grease or drill/grinder will get your rust. Prime the part you do as you go or you will keep doing it forever.
There are people here who build without a frame. The key is to tie the axle to the body in a safe package.
Pictures.
Easiest way is to open another window, get your album (I have my album saved in Favorites/bookmark) click on the picture you want to post, highlight the URL and copy.
Go back to the post window, paste, highlight, and click on the Img button. this will allow you to put more than one picture in the same post without using the Edit feature.
There are other ways to post the picture including push the Img button, paste, close tags.
