my 67 impala instrument cluster was rebuilt many years ago. It seems that every year I have a noisy speedo cable. Pull it out and lube it but not perfect. The speedo needle has a minor fluctuation but settles down after a bit of lube.
It seems to be a yearly ritual.
The transmission is 3 speed th350.
Any suggestions.?
I found this with a lifetime warranty Lokar 1500u at Summit.
