What's wrong with this picture Part 2, but much more serious this time.

I think it could be plated inside the frame & built back considerably stronger than it originally was and still be an invisible repair if properly executed..

That's what we're hoping for as well. I put the k-member back in (no steering or suspension), we braced-up the front of the car so that it could be moved (the car, not the frame), and with some large-wheel casters and a flatbed tow, it's now in the shop of a guy who builds street rods & pro touring cars for a living. Not sure when he will be able to get to it, but he understands the situation, and says he'll fit it into his schedule "somewhere".

(Re; "no steering or suspension": I haven't even gotten around to opening up the box and digging out the LCAs you sent back to me yet!)

frame on an austrlian mopar as standard does have zig zag section that bridges both sides of the rail from top to bottom and steel tube strengthening inside for the bolt hole.
it provides an ideal rust trap inside the rail so it rusts from the inside to the outside and cracks

The other day I ran across a Youtube video of someone in Oz who had opened-up the frame of a VF or VG, and in that video were pictures of the bracing you're talking about. When I mentioned this to the guy who's going to repair this frame, he asked me to send him a link so he could see it, and he promised to "do my best" to copy it.
