Keep in mind that the unrevised suspension is know for bounce and porposing issues. Resellers wishing to sell should limit the audiance to Z owners looking to return their cars to stock on dealer trades. Selling just the springs also makes sense and would likely result in a quicker sale. The upper shock mounts do have a market.
