Working on 71 dart swinger. I am putting ladder bars in it and was curious of some kind of hard measurement that could help me locate the rear in the factory location. The car has a hacked up spring relocation kit in it that was never finished and basically have nothing trusty to go off of. Or should I just put a tire under it and get myself a comfortable amount of clearance and go with that?

If someone could give me a measurement from the front of the front leaf spring perch, or in other words the back of that crossmember, to the centerline of the axle I think that would get me pretty close. looking to run a 28-10.5 tire.


thanks
