Welded seat rails

[Commy]

I have to contend with a few rust spots on the floor board of my ITB VW. They are in both corners were the seat rails are mounted to the rocker box. I don't think it is that big of a deal to remove the driver's side rail because I am going to need a way to fab up a mount for the seat. If I am wrong about this, let me know. The passenger side is a bit more difficult for me to understand. Do I have to remount the rails when I am done fixing the rust spots? Can I remove the two front seat guides that contain the locking pins? I ask this because they are a part of the seat mounting and have no structural meaning to the chasie. It would be a lot easier if they had simply bolted these to the car instead of welding them, but it is what it is.

Here is an image to give you an idea of what I am talking about, and also what happens when you take a northern car and try and convert it to an IT car.
