A "Hardtop" is a body style of a car popular from the early 50s through the 70s because it was missing the door pillar -- making the car look like a convertible top with the top up. They had a tendency of being a little noisier with the windows up, and were less desirable as drag racing cars as the elimination of the pillar made the car less rigid.
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.
