I've heard of "tall ball-joints" in relation to other cars to modify front-end geometry specifically for cornering but I've not particularly heard of a retro-fit for what you're trying to address. Sorry.
Tall ball joints are as mentioned to correct camber issues in cornering with a first gen Camaro and a third gen Nova. They will not correct his issue which is a bent frame.
Only solution is to put it on a rack and using hydraulic pressure push and pull the frame back into alignment. Then to reinforce the frame structurally by adding gussets or adding additional material to deepen and widen the frame member.
well ya I am so scared to get the frame pulled, the body is perfect ,the gaps are perfect , so I reinforced the frame big time so now I want to use adjustable control arms, off set control arms , the fame rails will not move anymore, just need to know what works … I need more positive camber
