Yep, I'm going to revisit this after I'm further along.
J. Robinson- I have had the very same thoughts, I know one thing about this wheel it was in a pretty good wreck. Someone straightened it but the scars are still there.
I worked on the roof for the last couple of days. These little brackets are for fixing the curvature of the roof. I welded those in then I'm attaching this 1/2" tubing in the arc of the roof, then I can lay the sheet metal on that. I slotted the tubing so the brackets slide inside it. When it's all in place and welded up I will trim the brackets so they will blend into the tubing.
