Help with speedometer cable?

[ghostvbhc]

I ordered a brand new speedometer cable and when I hooked it up, it didn't work. Now, I checked to see if everything was hooked up and tight and where the cable hooks up to the transmission, it feels as if it isn't hooking in all the way into the transmission and the speedometer isn't reading anything at all. And, I feel as if when I shift it into gear the speedometer cable is gonna end up getting chewed up because it looks like the cable isn't fitting right and it's hitting the bottom of the shifter. I have a three speed manual transmission in the floor. If anybody could help me with this, I'd appreciate it.
