Wanted Speedometer cable

I am looking for the speed cable pictured. (I think) I assume that there is only one of that sort.

We just bought our '64 and there are several things the previous owner did correct but several others he should be slapped for...he filled the cable housing with RTV?? Don't know for sure but I pulled out a huge chuck but the cable doesn't appear to be salvageable it.

Also, looking for the linkage cable for a pushbutton. The one we have is gummy, it works but needs replaced.
