shaving my drip rails, 73 dart

Well been really busy and broke, got a little bit done this weekend. And I do mean a little bit.
I ended up changing game plans, and rather then just welding a piece of metal to the roof, i have decided to cut into the skin a bit, and flush it in. In doing so, i discovered I don't like the position it puts me in, as far as welding from the backside (you will see this in a few pictures).
Basically. I am welding an extension to the roof sheet metal, then on the backside in the weather stripping track, tying the roof sheet metal to the structure. I didn't like this idea, so the next section, I am welding in a reinforcement bar, which i'll hide under the "extension", this bar will tie the structure to the roof sheet metal.

Hope that makes sense. Its a ***** of a project, but fun still, I think it will come out nice based on how this first section looks.
Amateur welder, think my welds are a hell of alot better, getting good penetration, very little porosity. Dunno what happened on this one, the porosity if so small, dunno. I did prep both pieces before welding. And I am getting good penetration on the backside/track weld.

Any questions or comments are welcome.
