    Mine leans about 1/4" left also and has since I've owned it. I have new front and rear springs, all new suspension components and it didn't change in the least when I moved the battery to the rear. I used a set of scales my boss used for quarter midget setup and the weights were LF 872, RF 872, LR 676, RR 677lbs respectively. I also attempted to cut a small amount more on the RH front spring and it didn't make a difference, so I have to assume it's the rear causing it which leads me to agree with the combination driver and gas tank offset theory.

    ...or, it could just be that the quarter panel arch is slightly lower on the left rear...:16suspect???

    I remember in the '80's the Escort diesel had a left rear mounted battery and the left rear spring was a much higher rating than the right rear.

    Good info.

    So what if I were to have a shackle that is longer on the left rear? Maybe like 1/4" to 1/2"...

    That sounds right. I don't have any issues w/ doors opening and closing.
    I just find it interesting to know its not unusual these cars to droop on drv side. And to feel my car don't have a real safety problem.

    It might be ok since you're only dealing with leaf springs. In the front, a significant change might put you in a different spot in the camber curve, but depending on how sloppy the front end is, that might not matter either.

    With those weights, there shouldn't have been any lean at all. Unless you did it without fuel and the driver in the car

    Every old car I've ever owned has had an offset rear. Not real noticeable until you start trying to cram big tires up under them. GMs seem to be a bit more obvious, the late '70s Malibus and Caprices I've owned all were offset. And you could really tell it w/ 8" rallys and 275/60s out back.

    Just checking back in to see what the consensus ended up being.

    And you know what I meant...:lolup:

    I also replaced all the bushings, and no door issues.

    I was measuring from fender lip to top of rim when doing my measurements.

    My comet does this too, it is offsett about a 1/2" but if I loosened the u bolts and slid the axle itself over a 1/4" would that hurt anything with driveshaft angles and whatnot????? I want to put 245/60r15 on the back but with the offset the driver side tire will rub:/

    Also a function of offset of the rim. Type "rim" in the search function to get some ideas.

    They are on an 8 inch rim and I'm guessing it has 4.5 backspace.
