Its good that you bring this up Albert. Are you speaking of actual spring coil spacers.....those rubber parts that are inserted between coils to bolster a sagging spring?........or are you speaking of the rubber spring "perch"....that goes at the top of the coil between the body and spring?
The spring perch above the spring actually came in a couple of varieties. There were thick ones with shaped cut-outs for the end of the coil to set into....and they wer for the coils whose end was left round.There were also ones made for the coils whose loose end was ground flat. There were different thicknesses. In a nut shell...you had sedans and wagons with flat and round in each. I believe the wagons were the thicker ones. Ray

Be very careful with that type of spacer. Those can damage the spring by creating a stress bend. Generally the rear springs do not sag very much with age on this vehicle. It is typically 10% on average. Usually it is a combination of poor camber on the rear..which drops the rear by 1/2" or more....and bad shocks...or worn out upper spring perch pads. Ray
