This Caterham throttle cable has been specially made to match the original part. The plastic square fitting will clip into the throttle body holder. The pedal box end has a 3D printed part that clips into the pedal box. The nipple on both ends match the original part. The short type cable is typically used on Rover RHD models. The longer cable is typically used on Duratec and Sigma models
