I didnt go back & reread your thread, but check the front height as well. If the front is higher on one side it can throw the rear off. There are different sized global west spacers, you may be able to correct it somewhat by mixing/match front spacers if its off in the front. This is fairly common on these cars. I have used spacers on front & rear on cars in the past to get them level side to side. I prefer to measure from the floor to the top of the fenders on all 4 corners. I have also found that stick edger blades (i own a landscape company) are great spacers for the rear leaf springs. The are the perfect length & have a hole in the middle for the locating stud. I paint them black, and stack them if needed to get the desired height. Plus they will slide in the perch without having to take everything apart, just losen the u bolt nuts & pry up on the rear end.
