My odometer (both trip and cumulative) has stopped going, although the speedometer is fine -- it's only 156K miles. I guess it's time to tackle the notorious odometer gear.
[It's a '93 sedan with automatic tranny. I don't know the ratio on the speedometer face because, long ago, I covered it with a new custom face (although credit goes to Dave Barton for creating such really nice faces) without the foresight of recording the number :-( .]

Can anyone suggest a source to buy the best quality replacement gears (I don't want to have to repeat this, if I can find a better than OEM replacement). I understand that more than one gear might be involved, so I'd like to replace or upgrade all potential future-failed gears.

Also, any suggested link to repair instructions would be appreciated.

Thanks all.
