Here's a link to a clip of a new chassis that Schwartz Extreme Performance is marketing... it's a complete bolt-on replacement using racecar suspension for '64-'72 GM A bodies. The 1st gen F body Camaro / Firebird / Nova etc. version is next. They've also got a '67-'70 Mustang and early GM truck version. We shot a piece for our show and thought it was cool. In fact, we're going to use the F-car version on our Royal Sport Camaro project. The best part about this chassis is that the parts are lo-buck but high performance.
