hey, I somehow lost a couple of the panels on the rear passenger side--the ground effect, isn't that what it's called? It was always scraping the curb, getting pretty chewed up, and one day it was just gone--it's probably somewhere on the side of 580. So how much should I expect to pay to get it replaced at either a Toyota dealer or a body shop? OR, should i get the parts online and snap them into place myself? how hard can it be, right? For the record, I've got a navy 2004 XB w/ sport suspension--cute as hell.
