My car is a 72, so I need the style with the gnurled socket. I wonder if it's worth trying to clean the connectors. How do these things fail?

I know the 73 ones fail because of ground. Having the thing make a natural ground to the fender was a terrible idea, I don't know what they were thinking. Try that first as well as cleaning. But do one at a time or you'll never know what worked. Otherwise the only other thing that can go wrong is the wire has disconnected from the pin in the socket. Also an easy enough fix if you can solder. My 67 Charger has the same type socket for the blinker, terrible design. But then again who thought they'd be around for 50 years

I don't think there are any other possibilities.

Learn something all the time on this site.
I never knew the '72 style used a threaded electrical connection like that. 45+ years around Mopars, and I'd never seen that.

I can tell you it was a lot of fun to break loose when I had no idea what I was working with, and it was half covered with underbody rust protection I had sprayed on in '93.
Any idea how this grounds?

Well as mentioned previously there is only one wire that goes to the bulb. The base is "supposed" to make ground to the fender and viola! With that amount of corrosion it is no wonder it doesn't work. If you want to test the cable, connect it to the blinker or if you want to be safe use one of those 12 volt power pack/battery jumpers. Clearly the end is hot/red and the base of the bulb socket is your ground. If it works with a good bulb in it, then it is not the cable. Most likely the piece where the cable socket makes contact with the piece that came off. What you may need is a blinker housing, not cable. Did I explain that correctly? My honest opinion ... I'd replace the entire thing. $50 you're done fooling around!!!!!!!!!!!!!!!!!!!!!!! www.ebay.com/itm/1968-72-MOPAR-FENDER-TURN-SIGNAL-INDICATOR-DART-DUSTER-DEMON-SATELLITE-GTX-/162285858573?hash=item25c8fdaf0d:g:5FgAAOSwbsBXjuX6&vxp=mtr

I think there is a screw that holds the metal base plate to the housing and provides your ground through the housing mounting to the fender metal. The screw head looks like it's rusted way. You may need to redrill and tap your housing and find a replacement screw.

I used a grinding wheel on the dremel and took the corroded tab down to good metal, ground the base of the bulb housing down to shiny metal, put it all back together and - nothing.
I haven't seen any sign of a screw holding the tab to the chrome housing though, so maybe "nothing" is to be expected after all.
Just buying a new one is a good suggestion, now that I know where the problem is, but $50 buys a lot of other stuff I need more, and I hate to be defeated in my fixing.

I know what you mean. Did you test the cable only to see if it is OK? And that is a rivet ... you could try to drill it and put a small screw in there. Nothing to loose at this point ... it doesn't work now.
