The Bug's speedo started making the dreaded death chatter, which means it's time to start looking for a replacement.
Unfortunately, rebuilt speedos are upwards of $200. I don't have that kind of money. Used are cheaper, but you really have no clue what you're getting when you go that route. And even the best used speedo is still a 50 year old bit of machinery.
Our old mechie, down in LA, has a used Ghia speedo listed for ~$70. That's not bad, but see above for why that might not be the best idea. Plus, Ghia speedos are slightly smaller than Bug speedos, so I'd have to make a bracket to get it to fit properly in my dash.
Ghia speedos also don't have an integrated fuel gauge. But I've had the Bug's sending unit disconnected pretty much since I bought it, so that's not really an issue.
I could also just buy a completely aftermarket VDO gauge and be done with it.
But I've never had a good experience with aftermarket anything. So I'm a little leery there.
