He's talking about the factory knock-outs that are in place on all of our trucks, at least the OBS ones. Most shops charge around $50 to $75 to knock these out if your truck needs it done to allow a proper alignment.

I've never had to do them myself so I can't give you more details, sorry. But in response to BadNewsSS, this is a legitimate deal on the OBS trucks, dunno about the newer ones.
