If you're using un-split or radius rods that meet near the middle up front all you'll require is a torque arm to keep from bending the radius rods.

If the radius rods are split and brought out to the frame rails where they are parallel, you can add torque arms similar to the top of a 4-bar setup.
That will control torque.
Then you'll need something to control lateral movement.

I find Panhard bars to be a very good answer here and have used them in front of and behind the rear axle on 32 framed cars.
Make them as long as possible and mount the frame bracket on the same side as the steering box.

P&J's triangulated 4-bars and their narrow in front rear radius rods work well, but they can create conflicts with other chassis mounted components.
Especially so the radius rods.
It can be difficult to get a decent sized muffler set up in an A chassis or 32 chassis running the long narrow at the front radius rods.
Whether P&J or a stock setup.

One thing you will want to engineer in is a rear sway bar.
This, whether you run a transverse leaf or coilovers in the back.
Decue Factory makes a nice small one that gives you the option of several mounting places.
