1960 rear end alignment issues

I know from past experience that the rear ends in the x frame cars tend be closer on the driver's side. On our 61 with 255 50 17 there is more space on the passenger side between the quarter panel and the tire.

I attempted to put this same tire and wheel on our 60 and it is much more off center than the 61. There is way too much room on the passenger side and I cant get the tire/wheel on the driver's side.

What is the proper way to square up the rear ends in these cars. Any help will be appreciated.

Thanks

I had that long skinny bar cut and then welded back with 1/2 inch less meat. That worked perfect for me 19 years ago and it is still holding. Sorry I dont know the name .

Thanks for the response. I guess you are talking about the panhard or track bar.

Do you happen to remember how much difference there was from side to side?

Thanks

The Panhard bar centers the rear end at stock ride height. If you have lowered your car (or if it has the original coil springs that it left the factory with) then those springs will be sagging an inch and half to two inches below stock ride height already. As such the rear end will not be centered in the frame. You can buy an adjustable Panhard bar from many suspension vendors like Hotchkiss that will allow you to center the rear whatever the ride height is.

Thanks Big Dave, I understand what you are saying. I also have a 61 and a 64 and all 3 are stock ride height with what I assume are the original springs. Only the 60 is off this far. I'm not sure an adjustable panhard bar would have enough adjustment to center the rear it is off so far.

It has been too many years to remember how much it was off.

I would examine it to see what the issue is. A former owner may have torched a spring to lower it resulting in the spring collapsing. You could also have control arms with the rubber bushings completely missing (which would be dangerous to drive). There could also be former collision damage that bent a suspension control arm. Any of these can cause the rear end to be off centered.

I drove this car only a couple miles before we took it apart. It seemed to drive very well. There are no signs of collision damage at all. We are going to look at things closer. I appreciate the help.
