I measured the trans cross member to the front of rear axle. Passenger side 73.75 inches, Driver's side 73.375 inches. Then I measured the leaf spring mount to leaf spring center. Both sides are 22.250. Finally, measured from axle pin locators across the body to opposite side and it was off by .250 inches with passenger side axle being longer. Next step will be to make and install a .250 shim on the driver's side and install on the leaf spring mount.. Loosening up all the rear mounts to eliminate binding when doing so. That might be a couple weeks while I address cooling issues.
