I changed out the rear coil springs on my 76 Electra and now I have a shake at 65-70mph. What went wrong here? I did notice that the springs did not just drop in. The holes in the top and bottom are mating with the areas on the chassis and axle, but it seems like maybe the spring needed to be spun around a little more for a symetrical fit. Does it matter how they go in. Closer coils of springs are at the top by the chassis.
