Hello, I'm restoring a kit car that has a fairly standard Cortina rear end with an Atlas axle.
It has the wobbly four link with the upper arms making a "V" shape.
I'm thinking I'd like to tighten up the side to side movement.
I assume a panhard rod is a no go as it will have a defined arc side to side movement that may not "agree" with the upper arms. Am I over thinking this?

Would Watts linkage work?
Would I need to modify the original four links with watts or can they stay as is?
Assume they wouldn't all need to be parallel with eachother?

Any help would be greatly appreciated.
