ADDCO Rear Sway Bar 3/4” or 7/8” Diameter?

I had/have the 3/4” Addco on my:

68 Dart conv with stock front sway bar, .87" torsion bars, stock leaf springs

68 cuda with stock front sway bar '94-2000 and then 1 1/8” front sway bar 2000-2011. But 1.00” front torsion bars with stock leaf spring.

if think it helped the Dart more.

I would not go 7/8” rear with stock front sway and torsion bars.

I don’t think I’d do 7/8” unless I was autocrossing with sticky wide tires and had big front sway bar and really big torsion bars
