Rallye dash and wiper switch question

Yes the 71 rally should have the metal reinforcement. My 71 Demon does. If you have a 71 wiper switch for the dash and it appears you have both 71 and 72 connector, why not de-pin the 72 harness and install the terminals in the respective correct points on the 71 connectors to use with the 71 switch. If you don’t already have a 71 switch might be easier to locate a 72 switch. Just my thought.
