I installed a set of OME coils on my truck three weeks ago. They were the same height. The FRONT coils on the 80 are unequal length because the spring perch locations on the front axle are different left to right because of the offset diff. This does not apply to the 100.
Seriously. Jack up the rear and check out the coils. Pull them if needed. We have exhausted the capacity of speculation here.
