I wish that it would have gone like i wanted it to. But it was a bit of worrying for this and that. I will tell you this it took much longer to install also waited for parts that i didn't want to do from the start. I spoke with persons. Wanted complete kit no headaches if needing this or that or trying to make things work. Just was learning lesson i guess but nothing horrible just working on car pains. Waiting for parts when i wanted it all at once is the part that just sucked. Live and learn

Would Recommend

Easy to install would definitely buy again
