Critique my cage

['85 LSX c10]

So i just got an 89 s10 blazer 2wd and am going to to a turbo ls swap and hope for about 700 whp i also recently bought a tubing bender and bend tech and i wanted to knwo what you all think of my cage, i have it set up so i can still have a rear bench seat or possibly even two racings seats in the back if you see any major safety concerns please point them out.

I would try to triangulate from the top of the B pillar, down to bottom of the C. As I am looking at it, nothing but the rear down bars in the back are keeping it from folding over in a frontal impact.
