I disagree with Hawkeye since Missouri is the hardest inspection I've ever tried to pass. Kansas City, St.Louis and their surrounding counties all have emission testing going back to 1967 (could be off a year or two). All of the lights (including side markers, reverse, etc.) have to function, tire tread depth is measured, brakes inspected, suspension inspected, horn, etc. My Roadrunner was failed for being about 1/4" below the top lip in brake fluid, and wiper blades the mechanic decided were too worn. Also, all pollution control equipment, for any year, must be installed & working, no changes to exhaust configuration (I had a '79 Trans Am rejected because I'd made it a true dual exhaust) and you cannot install any engine that was not at least originally available in that car/year.... so no '74 Hemi Satellites.
