A few weeks ago I swapped out my single adjustable panhard bar with an on car one that I had laying around. Obviously it a lot easier to center that axle with that one!
That one has rod ends (heim) on each end. That and the poly rear LCAs felt a bit squirrely on an 80 mile drive yesterday.
That said, I'm thinking about replacing the panhard bar's rod end (on the body side) with poly. Also, while I'm there, replace those LCAs with the stockers, which are rubber.
Any thoughts or advice on this?

The J&M’s have been on the mustang for nearly ten years now and it used to make 1/8 mile drag runs with them on. There was a nite and day difference in the launch for the better after they were installed and cornering was improved quit a bit as well. Don’t let the price tag fool you. The J&M’s were a little more expensive than theyb Founders but both look to be of the same design.
*Edit*
They are not loud at all. They sound the same as the oem.

Agree with Y2K.
I put the founders LCA on my Camaro recently and they give a better then stock ride.. Also replace panhard bar with Founders non- adjustable bar.
Well worth the money and better feel/ride of the rear end.
My stock LCA and Panhard bar were in good condition.

Interesting. I have the Founders poly-poly LCAs. I love the tubular design, but not the bind. I remember contacting Founders a few years ago about removing those bushings and pressing in some rubber and they said it couldn't be done with what I have.
I ordered a set of those LCAs along with the poly bushings to replace the rod-ends on my on car adjustable Founders panhard bar.

Lemme ask you this. How could you tell that the LCA’s with the poly bushings were binding? Sound? Feel? If I’ve ever expirenced it I’ve never noticed or didn’t know.

I guess I don't really know if they're binding as nothing is broken or snapped. High speed cornering has some oversteer that you don't get with the stock and you know those stockers aren't binding with it's rubber.

Not sure what kind of driving you're into, but I had those 3pc Founders arms on my [road course] track car and swapped them out after a couple years. The outer cups were soft at first, but they eventually hardened with time and felt about as hard as regular poly. The spherical ***** also swelled a bit and were no longer spherical, they had a flattened strip down the center and didn't articulate well. They were OK for a couple years but started to cause snap oversteer as time went on so I swapped to rod ended LCAs. They're fine for a street car, but I wouldn't recommend them if you're going to drive at 10/10ths on a track.
Side note: rod ended LCAs are really harsh on the street, but I don't think a rod ended panhard bar is that bad at all

I had the same problem. Bought some large washers and had the new hardware bolted them together overnight made them compress. Still on install I used a grinder with sanding disc to remove some of the rubber bushing to make it fit.

I'm sending them back. To hell with sanding and cutting and pressing and beating!!!! The stockers will be just fine for me.

You know what .... once I lubed everything up first they seem to compress much better, It'll be tight, but I think they'll work.
