Re: Rear Panhard Bar ?
I have both front and rear on my town sedan. The rear made a big difference; I noticed very little change after adding the front. The object is to stabilize against the sideways oscillations that are permitted by the transverse "buggy" spring shackles. I think this is most important in a heavy-back-end model, such as the town sedan.
I don't think it can hurt anything. it's set up when the car is at rest so that there is no load, or stress, when the body is centered where it's supposed to be. Although it sort of looks like it only works on the left side, it actually works across the entire car width. Ideally, the bar would span the width of the car, but I guess they couldn't figure out a way to do that with the Model A.
I was very impressed with the immediate improvement in how stable, or more modern, the car felt after I installed the rear Panhard. I would not be without it.
