Sway bar options? Matching components.

MOA said
From what I've read here, it's very important to match up sway bar to spring rates.

Here's what I have...

72 Dart swinger.

.990 torsion bar, HD 1" under 5 leaf springs from ESPO. 18x9 rims w/ 18x35x265 nitto 555 G2 tires. Rear springs located 1/2" inboard. Subframe connectors. Bilstein rcd shocks. Powersteering, 16:1 box. Having firm feel rebuild it.

Not planning to auto X this car, however, that's about how the car will be set up only slightly less aggressive.

Leaning towards hollow sway bars for reduced weight.
1-1/8 front, 7/8 rear?

1-1/8 front is a very good choice and I imagine 7/8 is fine for the rear from what I heard.
I have been told by others when I was shopping for my front sway bar to never even look at the hollow ones but then I was keeping my /six bars which are tiny. The solid 1 1/8 front held up the car fine and stopped the headers from scrapping on bumps. I suppose if you have the proper torsion bars something smaller or even hollow would be ok.
