My Toxic '74 Duster

For a car that is built to handle, the us cartool stuff is about the nicest, well fitting stuff out there. Subframe connectors are the minimum required in my opinion. The rest of the chassis stiffening is up to how hard you plan to push the car and how much power it will have. Also, welding, bracing, stiffening the k member as well as the lower control arms (if using stock parts) should be on your list for a corner carver. @72bluNblu and @autoxcuda are both great recourses here as well as @BergmanAutoCraft. Hope they chime in.
