Not baggin' on your chassis, because I think it's plenty strong. However, a couple of joints caught my attention - black circles.

Ending a structural member in the middle of another structural (unless it is tied through) is something I tried to avoid wherever possible.

Just a thought.

No problem, everything is still just tacked in place at this point so now is the time to find the bugs. I wondewred about those circled areas too. That's the way the SFI book recomends doing it. I figgured maybe that's supposed to be some sort of crumple Zone or sumpthin' ???? although it's purdy' close to my a$$ to be crumpling??

I typed this up while I was waiting for the puter' to become available again.........

My Son needs the internet so this might be old news by the time I get back on.

This is the side view of the green brace.(Made it straight). If I install the Green brace would the short one I have tacked in under it now be ness.? Or would I be better off eliminating the short ones tacked in now and go with the full length Green brace adding and "X" between the Green bars? Then a yellow "X" from the first pic. and as Jack suggested an "X" either on the back slope of the back half rails or maybe in the far rear flat part of the rails? I will be putting a parachute brace back there so if I put an "X" way in the back I would have to integrate the chute brace with the "X" brace.

Another thought was use the Green brace with an "X". Then replacing the existing braces with an "X" that extends from a point on the outside corner of the ''right'' main loop to the "left" hump of the back half rail (Where the existing brace is tacked on now) ........ and "left Main hoop to "Right" hump. (Pink "X" right hand pic.) This "X" would be lower than the green braces and at a lower angle creating more triangulation of the bars and maybe shoring up the cage area at the same time?

Still going with the yellow "X" from pic. #1 and the "X" Jack suggested for the back side of the frame rails.

If I'm reading the book right that I need the Green braces (If they are to be the main ''Cage to Frame'' supports to be 1 5/8" tube ......... or is this "elective" territory as far as certification? Tech guy said I can use chromoly on my mild steel chassis if I want to. I've only used chromoly tube for bolt on suspension parts so far.
