Keep Up The Good Business
This ignition switch is a direct fit. Once I got it installed it worked flawlessly just like the many parts purchased in the past. I am a repeat offender when it comes to buying auto parts from 1Aauto. My only beef is this part took longer than normal. I can't get use to that. Please correct that. Im use to less than a week. You still get 5 stars.
