Hi Shayne, Dan and Josh, thanks for the replies!
Shayne, it's good to know that there aren't any replacement parts available for these. I'm surprised that I managed to employ a hint of wisdom and left it intact until finding out whether or not I could rebuild it! Although I wasn't wise enough to leave the inside firewall cover unharmed. That's a neat photo of your assemblies by the way.
Dan, yeah that wire is looking pretty sorry!

Some day I'll put in a whole new harness, but not at the moment. Maybe I'll check that wire out and put some new electrical tape on it.
Josh, thanks for the offer on your unit from your '70 with the 302. I think my assembly isn't worn out quite enough for me to consider swapping it for another used unit, and I have a '67 parts truck that I can scavenge first. But thanks for the offer and I'll keep it in mind. If your assembly is easy to grab and inspect, I'd be curious to know if there's any play in it. Like when you grab the shaft in one hand and the mount in the other, and wiggle it around, does it give at all?
Thanks again folks!
