I purchased the new spring and the shop is installing those as we speak (doing suspension and exhaust install same time).
The part # I bought was one complete set (not single spring as I thought) in that gold plastic body (my 08 is in all black plastic) with spring assembly. It looks like both springs are inside (and made them into one complete set) but it's hard to see (and my shop isn't really happy with me right now so I couldn't ask him too much or taking pictures). I'll let you guys know how it feels after I pick up my car.
