The early Milanos came with quite long (18" free length) rear springs that give it a very high rear. An easy mod is to chop one coil off the rear springs: this lowers the rear about 1" and stiffens the springs by about 10%.
I did this on my old '87 Milano: it made the car look more level and didn't cause any problems.
Enjoyed looking through the thread. Nice work bringing her back to life. I'm in the process of a refresh on my 20+ year ownership of an '86 Graduate. Had the engine, transmission and rear end "re-sealed", ha! It doesn't leak today.
