Look for them on V6 cars. I think most of the mid 90s V6 Taurus used them, some mustangs and Econolines. Many other applications too but they bolt down solid and have the wrong mounting. I get them for $10 if I pull them myself, $20 if they pull them. They are far superior in every way to any Delco and really how smart do you have to be to just run one more wire from a key on source.
