I was cleaning my quarter power window assy. and found that there are different springs on them from one side to the other.
One side is a lighter gauge and only has 4 coils while the other is heavy gauge and has 5 coils. I have owned the car since 1980 and it seems to not have been tampered with in that area, the sound deading was all over these parts before I cleaned them as well plastic sheet covering under the panel. Anyone know what spring is correct? The windows did work in 1983 when the car was last running, but I don't remember how well!!
