68 Barracuda Notchback

Did you just do the tire well or the whole floor? That is the only place i have rust thru is around the tank bracket on the tire well. didn't know if the tire well floor patch is easy to put in or i should just do the whole floor.
I did the tire well around 15 years back and entire floor over the last year. For tire well I butt welded the patch panel in with seam a couple inches up from the bottom. It would be better to do entire trunk floor, better results, and can also clean out paint insides of rear frame rails. Here is my spare tire well patch project:
