Continental Imports might be cajoled into selling you the odometer gear at an inflated price, BUT they won't give you a refund it you order the wrong part or mess up the installation. They really want you to send them the speedometer unit and they'll do the job, replace ALL the gears and take care of a couple of other gotchas in waiting. Another place which can rebuild it is speedometer.com, who I used some years back. Like Continental, they do more than just replace the gears.
