don't have experience with those, but they don't have sway bar holes also you will want to use these bushings from speedway

The stock rear suspension in g bodies is designed to rely on the flexing on the stamped arms and the deflection of the rubber bushings to prevent binding and snap oversteer. For just a street cruiser, boxed rear arms are unnecessary. Boxed arms together with stiff poly bushings will cause binding issues and just a bad idea. That combo causes the LCA, frame mounts to flex and twist instead of the arms and bushings besides binding. Monte oracle has the right idea to use spherical bearings instead of plain poly bushings, they allow a secondary axis of rotation to prevent binding.

Now a few other posters will disagree with this but do not listen to them. These people know they have a bad setup but are in denial about it and will give you bad advice.

i have the southside machine control arms with poly bushings, i would have used these instead but the make there own bushings for the arm i have, so i only was able to use 2 of them on the upper rear, and im hoping it will be good enough to help with the binding, also the guy at southside said lowering the car really help with binding issues, just some info that may help you.
