not happy (Question)
I got a 67 Fairlane and it is unibody. I am wondering if there is any way to check the underneath for squareness or bends or whatever you call it. The car leans and I wanna make sure it is not the main structure is there a machine or something to tell... I am just not knowing what to do or where to start. It is about an inch on one side higher than the other. It is pretty much the same height front to back on one side. Like the front right and rear right are the close to same and the front left and back left are close to same. right side of car is
25 3/4 and the left 24 3/4.. Hope I didnt confuse you... If it is the unibody can it be straightened?

A quick trip to the body shop with a frame machine, will tell you what you need to know, but I would suspect sagging springs if you don't have obvious body damage. If it were mine I would jack the car up on a flat shop floor and place 4 identical jack stands under the car, catching the unibody at exactly the same points on both sides. Check the distance to the floor from the same reference points on the body, on sides.
If the body only sits on three jack stands, it is likely twisted. If it sits evenly on all 4 stands and you find a difference in one of your reference points, it could mean more serious damage to the unibody/suspension mounts. If everything still looks good then check the clearance from the bottom of the tires to the floor on both sides. Sometimes a sagging spring will show up this way.
I'm sure you have checked, but are all the tires the same size/brand and are they equally inflated?

This is very common among Mustangs, Falcons, Fairlanes and such. Unless you see evidence of frame damage or know it was used as a drag car that really got some good bite that would twist the frame I suspect it is in the springs. I'll be surprised if it isn't.
