Did you measure diagonally between both frame rails? For instance from the rear leaf spring mounting point to one of the holes on the front of the other frame rail? I double check my diagonal measurements and have never had that type of problem. Did you replace any other sheetmetal? Is your suspension new, old, or possibly swapped leaf springs?

its square. ever thing has been replaced. the suspension is old but i tryed switching sides with the springs it did nothing

Where did you measure from? Are the shackles the same length on each side (some look the same but bolt holes are spaced differently). Is the car on shop wheels that may have different size tires?

If measurements are square and level, then you should have no problem. I think there must be an overlooked detail somewhere. Do you have any pictures of your work that you could share with us to further investigate the problem?

three pics above will give you your reference points. Go over them from the start. If you cant see well enough by saving them to your pics or folder email me and I will send them to you.

Which side is off? Is/was this a race car? Is this a convertable? Big block car?

I have had to straighten out small block cars that were crooked from racing prior to replacing sheetmetal and frame rails. If your body had been beat during its previous life, it may have had a bit of twist, and may have not provided a good reference when replacing the rail. I just repaired a car in which the right side was twisted so bad that there was no door gap. This is only a speculation in your case.

From what I've found, just about every body out there has some twist, no matter what the history was. Some are worse than others.

First, those are not control points for measurements. The repo pan at the bumper mount, is most likely not the correct shape or dimension. Check it against the factory specs.
