More specifically within the Moparwiki, it is a listing of sizes (Length, width, height...), capacities (Fuel, oil, engine coolant...), weights (vehicle weight, engine weight....), and other consistent specifics for the topic item.
Because of recent spam attacks on Mediawiki sites by the tens of thousands of spammers concerned with the length, girth and hardness of our Johnsons, we have had to temporarily disable new registrations and editing until measures can be taken to ensure there is no further vandalism of this site. We apologize for the assholes out there that don't have better things to do, and will find a work around soon. Meanwhile, there are still thousands of MoparWiki pages containing a wealth of information.
