[1960HDGMC]

Hello, I have a 1/2 ton 1960 GMC with torsion bar front suspension. It sways when you take a curve. I have contacted sway bar makers and they all say there is, was and probably can not be a sway bar for these trucks. Rear sways are out there, just not front sway bars. Then why do I see bosses for the sway bars (that do not exist) on the lower A-Arms?
I wonder why I cant just get a set of 3/4 ton truck torsion bars and swap them onto my truck. Surely that would tighten up the front end a little and help in the corners. Is a torsion bar swap a pain in the rear end, or can I manage it in a home garage?
The truck is set to factory ride height and rides like a 1959 Caddy,because it pretty much has the same front suspension. Will I lose the smoothness if I can even manage to find and install 3/4 ton bars? I want to keep factory ride height after swap.
Thanks for any ideas, Greg Mead
