Speedo cable replacement?
Just replaced the speedo gear (and adapter seals) in my Scamp w/ 4.30 gears. Bought a 44 tooth gear from Cope and the seals. Unfortunately the more odd ball gears are expensive ($70+ vs $20 or so).
Here's a diagram of the adapter. Your leak is most likely the small oil seal...but the O-ring seal could be dry too if it's old...both should be replaced when swapping the gear.
As well here's a speedo pinion chart. Match up your tire height to your gear ratio and you've got corresponding gear part# you need, the last 2 dig are the # of teeth on the gear....if you can find one that's within 1-2 teeth it'll get you pretty close w/ speedometer accuracy.

Again, Cope Trans. hooked me up with what I needed!
