Do you have extra wide tires on?

I ask because mine rubbed both inside the wheel wells and on the fender lip.

It was mostly the fender lip rubbing against the outside of the tire wall that caused this and it was hard to see but it was very evident after I used tire black.

What I noticed then after driving was that a part of the inner fender was loaded with that tire black stuff. In my case it was just a little rub (a rib on the sidewall of the tire) and I was able to lightly grind off the offending overhang of the fender without getting into the area where the inner and outer fenders are welded together.

Anyway problem solved for me.

I'm guessing you have the wrong shackles on your car. I just went out and measured mine (hard to get exact) but real close to 3 1/2" C-C. Mine are Hotchkis, but I don't believe they were different than stock. I can easily get my fingers between the spring eye and the frame rail with a little extra wiggle room at ride height.

Shackles that are too short would definitely explain why you had the same problem with 2 different sets of springs.

edit - Well scratch that. Just did a search and someone measured a stock shackle off of the car - 3 1/8" C-C

No sir, the tires are not an issue here at all. This car is like the month after it was built,,,,,,,,,except the springs I thought were sagging, being 44 years old. Now the new expensive ones are worse!

So,,,,,, new correct springs, new bushings,,,,,, what else is there but the shackles? Would you crawl under there and get the center to center dimension?
What are the chances that this new set of springs are just weak????

You said the shackles have an "S" in them- not sure what you mean- stock shackles are just two straight pieces- one in each side.

Oh man,, sorry to be away so long Chris but I've been checking out your gorgeous car.

It seems to me that if all is as intended, the spring eye shouldn't hit regardless of load. The bump stops above the axle would stop excessive movement. Also the pinion snubber might get involved too. But those would happen with crazy-heavy load, static or dynamic.
Something isn't as designed. Sure would love some pictures.

Here's mine. I just went under there and pulled the gas tank for this shot.
All original except the exhaust. And it's sitting on jack stands under the axle.


The other side.




Also notice, for what it's worth, the top of the tire is visible when on the ground. These are 16" wheels, 50 series gatorbacks.
I notice yours are much more hidden.


AND HOW'S THE WEATHER down there? Ours is great. Normal rain.

No sir, stock shackles aren't just straight pieces. The "S" is stamped in the outboard side of each half of the shackle



Hopefully, I did the links right~~~

Ohh- you're talking about the dimple- I thought maybe you had offset shackles or something. Most aftermarket shackles like you get with a suspension upgrade kit are just 1/4" or so thick plate.

ID:	31967Well, I can't take pics like that now. One spring is out of the car, and the tank is almost full of fuel, but my shackles only hang like that when the car is jacked up, and the rear end is just hanging on the springs. In these pics, you can see to the right of the hole in the subframe where the shackle bushings go, where the top of the spring eye has been hitting. The left rear, I believe is worse.


I guess I haven't figure out how to post pics like you're doing Fred.

Chris, those shots are from my web site using the little yellow box above the typing box. It requires a URL. The other way is to join up by paying your money. You can tell those who did, like me, because our names appear in gold. That lets you upload from your computer.
So, for now just keep using your picture service.

Again Chris, I only see two possible causes; spring flat or shackles too short.

These are the original, correct shackles for this car. Can I find/buy longer ones, that aren't those huge, long 1/4" things?

Good job on the picture Chris, but the top one didn't come through. I'll have to get back under there to compare my dimensions but yours look way too small. Maybe you can change them for longer ones. Also, no mail has come in to me.

Those are new bushings? I don't see the steel sleeve going through the middle of them.
