I just replaced all my front suspension and took my lower control arms off but reused them as they were fine. When I took it to get aligned they said they couldn't do it because I didn't have eccentric bolts for the LCA's. I just put the stock bolts back in. The body is slotted though I would think they could just loosen the bolts and knock it where they need it to be. I replaced it all with stock parts and its not lowered so I don't really know why I would need eccentric bolts?
