Rear sway bar with tubular arms

[KarateCrotch]

I have a 85 Monte with a ‘00 cobra r 8.8 with trick chassis instant center kit tubular lowers, I’ve already got the upper shock tower brace felt a big difference but still have a good amount of roll. I want to install a sway bar but don’t know how to go about it can anyone send me in the right direction

And before anyone asks why didn’t I just throw in a gm 8.5 I had the rear end laying around already and wanted that lsd with disc brakes 😂🤷🏽‍♂️

The easiest option is something of this nature. On mine I'm going the ARB route.
You can also do the Blazer rear bar which some here have done. I picked one up but the arms are in the way of my exhaust.

Curious, isn't a 00 Cobra independent rear? How did a shock tower improve the feel? Was the frame moving opposite to each other under the trunk previous? I can only imagine a shock tower brace making it stronger if they tried to move to or from each other. Not picturing how this supports up or down.

Your thread title caught my attention. I had the same thoughts with my UMI lowers. Expecting a flat surface to connect to a round surface is just asking for a broken fastener.
In this case consider a Blazer sway bar which uses the axle housing instead of the control arm. I have not resolved this yet since I have a panhard bar mount taking up the space on my axle housing. Maybe it will work on yours.

I'm using the Hellwig sway bar. The only change I made was to use rod ends to attach to the frame rather than the rubber bushings.
