Greetings. Well, with the best-laid plans, I was installing an after-market radio in my 2014 Subaru Forester. All was going as well as could be expected when the little copper piece that fits between the airflow control nob and the wire harness fell into the abyss. My question is, does anyone know where I could get another copper piece to replace it? I could go to the junkyard, but my first choice would be simply ordering one. Thanks ahead of time for your help.
