Jack's Comments:

This is the alternator wire harness retaining clip commonly found on 1965-1969 Ford Autolite alternators.  

In the second picture it's compared to an original metal/vinyl original clip. The third picture shows a different version of this clip that is usually only found on 1965-66 Fords. It just like this clip but the looped end had a molded black plastic cover (not available in reproduction). 

Concours Notes:
1) The second to the last pictures shows how this clip was installed on 1965-66 Mustang.
2) The last picture shows the clip installed correctly for a 1968-1969 alternator. Notice the second strap/clip used was a black plastic type that was strapped to the harness with 1/2 wide cloth tape.
3) 1969-70 BOSS 429's did not use this clip.
