1-1/8 & 1-1/4 front sway bar vs factory 7/8?

I can let you know my impression of the Hotchkis bar in a few days. I’m in the middle of installing one on my 68 Dart
(And taking off a factory bar that had poly mounts and end links).
The Hotchkis bar does require you to use their weld on brackets for the control arms, and they have weld on brackets for the sway bar mounts as well. I’ll have mine back on the road in a few days. I got a second set of lower control arms and set them up for the Hotchkis install , rather than welding additional tabs on to my arms that have the factory tabs. I’ll probably sell them once the new setup has been tested.
