Okay, forgive my ignorance please. I'm gifted with an embarrassing IQ (higher than my credit score anyway), but at 53 years, I'm still an idiot. The more I learn, the more I realize how much I don't know. What's the difference between a slab side vs a fuselage body? And which one best describes mine? 73 Newport Custom 4dr post. I call it a lead sled, it's heavy as all get out (sticker inside the door says 6100 lbs! OMFingG! No wonder it's so slow! Is that a typo? Title says 4200, which is correct?) and it has an acre long hood and trunk. I thought fuselage bodies were coke-bottle shaped, like Chargers, Cudas, Chevelles, etc.
