Only advice i have is the square plastic slides into a rubber tube that pulls off the cable.
Rubber and end could be swapped from one cable to another,..
if you have a spare cable that won't fit your ap.
Go to hobbylobby or a good hardware store that has a selection of 'hobby' brass tubing and look for a piece that has a similar cross section. Alternatively, get a nylon fastener or bolt and use a dremel or small black plane or similar tool and square it up. It would probably take all of 15 minutes...
It seems likely that my cloak of invisibilty is still firmly intact,
but it's possible he stopped postiing because it worked great and he no longer needs us.
orr it was such a simple fix

I had a similar problem yesterday, screwed the speedo cable on and still didn't have a speedometer.
Unscrewed it to find the plastic, square peg missing.
I pulled one out of another (with my fingers, no special tools, ha)
flipped it for fun and shoved it into the cable of the '84 Rabbit project.
Taa daa speedometer/odometer.
Something else I'll need to keep a spare of and remember where I put it, ha.
Oh well, a square peg doesn't take up much room.
