There should be a plastic gear on the end of the cxable. Which will be driven by another gear in the transmission. These come with different tooth counts to allow you to correct your speedometer.

Use a pair of needlenose t0 get hold of it and carefully pull out.If you lose it it may be gone for good as another member found out on his 55 Fairlane.If the cable is like the passenger car (1957-up)ones at the trans end there should be a clip used to hold the gear onto rhe end of the cable before installing.

  

the speedo cable that i got from lmc dosent have a clip or anything on there on the picture there i have the first one it screws right on to the trans but once i start driving it dosent spin what am i missing
