So, last weekend, I replaced the springs in the front of my 87. The old ones were 4-5 inches shorter than the new ones. There were 4-5 inch plugs that were inside the tube above the spring. The old springs were wound like a progressive spring so I am guessing they are a different brand like a Sonic? Anyway, I didn't use the spacer I just inverted the washer with the lip in it and used the factory cup under the threaded plugs. It sits right and rides nice. I am just curious if the PO replaced the old springs with the wrong ones or were they also worn out because with out air it was bottoming out in the driveway.
