I finally got all my parts to get the speedometer operational again. Spent most of the afternoon under the car trying to fish out the broken-off drive gear from the tail shaft. Took a couple of hours and a few beers.
Here is what happens when you install headers and don't take into consideration how close they are to important stuff like...oh, I don't know...maybe speedometer cables?
New parts ready to go in
And here is a link to a fun little video. I had to resort to using the video camera on my phone to be able to see into the hole to figure out where the gear was and what I needed to do to get it out.

Finally got it out and the rest of the install was uneventful. Glad to have a fully functional instrument panel again!
