Recommendations steering box 70 Dart

Already posted before bout my 70 dart. My question is I’m getting tubular uppers arms
And im thinking about a PST 24:1 steering box. I’m not so sure that there is great advantage to perf lca’s
Recap:
Front fat sway bar
Stabilizer rear bar
KYB gas adjust shocks
SS springs
Fat torsion bars
Poly bushings
Really good tires
Upper arms
PST 24:1 steering box
A few other lesser items
I’m into quality parts and have spent way out of my budget
On the Dart. If lca’s are icing on the cake I will probably pass. My goal is to have excellent handling and power.
