Help Please! Sagging Front end, can't adjust Ride Height at all.

The pretzel effect, seen a few cars turned into a pretzel before the frame was tied and cage welded in.

I has to fix my red 66 Charger after racing it for a few years after I removed the 6pt bar and did not get around to doing the new cage. It went out of square when I removed the frame ties lol. Major bummer!
