How to make this Dart Handle?

Had a lot of fun and have never been able to push the car even close to that hard on the street. 6 cyl tors. bars 1 1/16 Super Bee Front Sway bars and Lift bars in the back that eliminated a lot of sway but I think I need to loosen them up some as they seem to tie up the rear suspension. Look like traction bar but clamp tight to front of spring. Car does not lean at all just slides sideways with the accelerator pedal. Top speed on track was 50 mph. 1/2 mi track with fig 8 in the middle is what we used Sunday.
