Thanks. They must go between the leaf spring and the shackle ?

The two with the short bolts appear to be the rears and bolt in place of the rear axle spring perch. The two without bolts (bolts are missing, but should be fairly standard) should be about a quarter inch narrower than the rears. They bolt through the spring perch holes (In the axle!) with a long heavy-duty bolt that also holds the wishbone underneath the axle.
I cannot be certain without a size scale, but that is what they look like. I have seen a few pictures of these on cars over the years. And some years back, someone posted a couple ads for them on our forum.
They look neat, but I don't think I would want to try using them. I suspect they may have a similar "stability" issue as another common early type shock absorber made for model Ts. The "suspended from a spring in a can" shocks have resulted in a few fatal model T accidents. These would make great wall-hangers mounted between empty rear housings and front axle axle and springs. The rears might be okay to use on modern roads. However the fronts at modern road speeds likely could oscillate and result in loss of control or even front axle collapse.

These I think are fairly rare. I have only seen a handful of them in nearly fifty years of playing with model Ts (probably seen thousands of front and rear ends at swap meets?). They really should be preserved, and seen. Just not used.

As I go to post, I see you added a comment/question. These go between the shackle and the axle, replacing the perch. Not between the leaf spring and shackle.

I own a NOS set of these as well. The guy who sold them to me some 40 years ago called them Grey Ghosts. My front pair is slightly different in that the “U” extends further horizontally.

The way they are supposed to work is by providing a different natural frequency of the two Ford springs. The two frequencies will tend to dampen the ride. I never used mine because leaf springs by their rubbing provide some damping without a shock absorber.

One of my customers has a set on the rear of his roadster. Guess they work ok.
I know the voices aren't real but damn they have some good ideas! :roll:

I don't know anything about these but they look like they are for the rear. The pictures, from an MTFCA thread, of the front axle shows double set
