Used handbrake lever assembly from a late S3/S4 spider. This handbrake will fit any 105 series car post 1968 but may not be the correct colour or handgrip.
The mechanism in the lever is working. However, it is missing the bolt through the base of the arm that locates into the bracket so this would need to be used from your current handbrake as well as the locating lug for the ratchet arm.
