Speedometer cable leaking and its New

Thanks :D

Could be in the housing where the speedo inserts. There should be a seal in there as well that could be worn.

Need to find that diagram in one of these books...
That would be great if you can find a diagram.
My original cable was swapped for aftermarket so I had no way to compare them. so your saying there is a seal inside the body of that cable end? So remove cir clips and it’s in there?
Maybe they forgot to install it.?
