Almost half a century old, improving the handling of the 1964-67 GM A-Body isn't particularly difficult. Without as much as a front anti-sway bar, the setup on our '64 Chevelle mule speaks for itself, leaving plenty of room to work with. Rather than give it a moderate makeover, we jumped at the opportunity to upgrade handling with a gStreet coil-over conversion from Chris Alston Chassisworks.
