MG TC Chassis Strengthening Plates. As introduced by the factory on later TC's to progressively change stiffness of chassis rails between channel section and box section adjacent to the handbrake cross tube thereby reducing tendancy of chassis to crack at this point through fatigue. Plates are laser cut from 3mm steel plate and folded to form a channel with 12mm flanges to fit inside the channel as the original strengtheners. Plates are in self colour for welding into place.. Price is for a pair. .
