Welcome aboard from NJ and a long time former owner of an 82 Ramcharger. Owned it for 23 years, and then gave it to my younger brother. What a great truck!
I presume you want the factory one that is held by a spring to help avoid breakage. If that's the case, I'd try a bone yard. If you could accept a stationary one that is close, they use to have them at (
www.jcwhitney.com). They even had some that lit up at one time. Good luck. Let's see some more pictures of that old Dodge!

I just tried jcwhitney and they don't have them anymore. But I googled them and as you probably already know, ebay, amazon, ect... yes but ain't cheap!
