About a year ago I redid a factory clock for the 67 Gp convertible. Went with a Quartz Conversion kit. First time something with the gears was jacked up and it was slow and eventually broke. But I put a new one in and it’s still ticking perfectly a year later! They make them for almost anything out there to my knowledge.
Here’s my video testing it before putting the case on.

I could entertain doing electric clock conversions for people, but would have to figure out how much to charge.
