'Z' Bracket mirror extension for use with Tenon Plate RTR9149. This 'Z' bracket is bolted to the forward facing extension to which a bullet type mirror or similar can be attached. Part number 222-355 is a suitable part. The tenon plate is sandwiched between the stanchion and the windscreen frame.

This guide plate RTR9149 to which this 'Z' bracket is bolted, is flat and can be used on both left hand drive cars and right hand drive cars. It is recommended that this 'Z' bracket is added to the tenon plate on cars where side screens are to be used as the cloth covering at the front of the side screen may hit the mirror when opened, without it.
