I bought this years ago for my 280zx, as the site listed it as a fit. After extensive engine work / etc, measured up and found out it only works on z, not zx models. This has 36-way adjustable dampening and height. Booklets, certificates, and tools included. Been kept inside, cheapest I can find this kit for is $980 online, will sell mine for $725 + shipping obo.
