both. first time, the jaw was trashed but also cabling was trashed and kinked
so you may as well buy a whole new regulator (sans motor). 2nd and 3rd
time was for relatives and it was jaws only so easy fix. jaws are cheap but
shipping was a little annoying, so i bought half dozen and just drilled the big
rivet out, and put them in ziplock ready for use.
