help me "appraise" some parts.

[ArisESQ]

im gonna try and sell a set of hotchkis 2 inch lowering leaf springs, with bilstein shocks, and a new in box competition engineering slide-a-link traction bar kit...the springs and shocks were on the car for around 2,000 miles of driving, so they are still pretty new.

what do you think a fair price for the springs and the shocks is? just wanted to get some opinions before i posted them up.
