Been working on this as I can. Complete bolt in design, uses the factory mounting holes and is one solid rail front to rear. Using a solid rail that contours the floor pan and seat brackets is the only way I see for this to be strong enough to keep the integrity close to the original design and where I'd be comfortable offering it.
All bends, no welding and I'll use a HSLA material.
Still a bit to go, but close.

I'd buy this in a heartbeat, I'm definitely concerned with the homemade weld + flatbar sticking back approach when it comes to holding the seat (and you) in place in a collision. This seems like a much higher strength approach. Let me put my money where my mouth is please
