My first frame rotted in the same spot in the same way. It's a difficult fix, and really needs to be cut open to see how bad the rot is. I mean, remove the fuel lines, and go at it with an angle grinder until you find good metal, then weld in custom cut pieces to make it whole.
As you do the cutting, be careful how you support the frame. It should be on jackstands, both fore and aft of the repair area. The body will keep it roughly aligned, but you don't want it to distort too much while you cut it open.
For reference, i conducted that repair, then a few years later, replaced the whole frame, because I felt it was easier.
