VHT, while your description is undoubtedly crystal clear to you "...toward the top..." and "...going to gusset from the bottom..." leaves a lot to the imagination. Now I'm not a chassis designer, but for me to offer any suggestion on the strength of a fabricated joint requires surety that we're talking apples & apples on the approach, nothing left to imagination. I'd suggest that at a minimum you post pictures of the existing chassis, marked or taped to show cut lines, and maybe cardboard mock-ups of your proposed joints; or maybe dimensioned sketches with a detailed description of how you plan to proceed. No disrespect intended, but like Chopt50wgn says, your life, and the lives of others that you're racing, depend on your design and execution being spot on.
