I think there are so many options available today for this kit, that not many people even bother with the kit's chassis; just snag another from your kit stash or check the "Trading Post" or other sources for a better chassis solution. The Revell '66 GTO is the first obvious choice, but look at the AMT and Lindberg '66/'67 Cutlasses, AMT,Revell,Lindberg '66/'67 Chevelles for example. Any of these and many others offer much nicer detail and realism. I've found them at swap meets for cheap, where the owner had other plans for the body; slammer build, or racing chassis swap, etc.
