55.2-59 Sway bar recomendations

[Roarinrat]

Hi
I’m really pleased with my 56 GMC, apart from the body roll during turns.
I have Mustang II front end, and a Ford 9” rear end with a four link and panhard rod. I’m happy with the spring rates because the truck rides well, with a good stance, and no uneven tire wear.
From what I have read so far I think I need at least a front sway bar, but what diameter, and I’m unsure where the sway bar ends would connect to the pressed steel wishbones.
I’d appreciate your thoughts and recommendations, and which kits or own design solutions you’ve come up with.
Thanks
