Leaf spring torque link?

[68Formula]

I'd leave them as soft rubber. Looks like the leaf and bar do not have the same IC points so some deflection in the bushing is needed.

So something like this:

or this:

would still cause binding?

Looks like it is going to bind? Did not bind in Jimmy's car.

That the housing floats with the upper link...like the spring is the lower link and in a 4 link system.

I think they ran this same system on an Austin Healy as well.
