So, is the framerail you're talking about the longitudinal, or inner rocker panel, or whatever? From what I've seen so far, most of the rust seems to be confined to the suspension ear, jack point, the lower firewall near there, under the passenger seat at the rear, and the longitudinal part right there.
Just those parts.
Of course, I'm sure I'll find more rust when I get into it. It's always there, right?
I'm sure you'll be getting your repair done before I do, Brad. If you have measurements, that would be great.
Lawrence,
I think a previous owner welded or brazed the crack. There are other repairs on the same piece as well. With all the work they must have done on it, I don't know why they didn't just replace the piece to begin with.
