Sorry it's been awhile since I've been able to go out to the garage and work on my A. The starter is still not working but, on a good note, I found an oval speedometer in one of the many boxes of parts I got out of the previous owners shop. Most of the numbers are missing off of the odometer and trip meter. I found all the stuff that needs to be replaced from Bert's. My only question is, what lubricant should I use on the gears inside the speedometer? I've read everything from the mystery oil, 3 in 1, graphite, and just WD-40. Just curious of what would be the best option. As always, Thank you for your help.
