If you've got good springs (18+, 58+) you MIGHT get a little coin for em, though I gave mine to my neighbor, who had the weakest ones (I think) available. DS is worth something...don't know what.
The other stuff, maybe somebody who needs stock parts would be interested. My stock TB's, CA's, sway bar links, etc. are in a storage room in my garage.
Side steps I sent to a guy in California for the cost of shipping. Bumpers...don't have any takers for those yet. Wheels/tires I sold to my dealership for $500.
Don't plan on paying off your mortgage with any of it.
