Refer your PM ~ Some cars had 1 central P Clip holding metal vacuum cross pipe & some 2 between the Reservac tank & heater vacuum tank. My car had two exactly like this. (not my car - sorry I did not take a pic.). I re-plated my pipe as my original was plated.







My car with valance attached correctly with self tappers & copper washers.















Offering up valance on a friend's car.






Hope this helps.

 

Perfect! Thank you very very much
