excellent price,
For the money it is HALF the cost of the ford oem replacement. I called my local stealership and they wanted 53~+/- dollarie doos and then i remembered this website from the youtube videos on how to install parts. 23 bucks, works like a charm , fixed my rear tail lights turning on then off at random when i pushed the brake. this is worth it. so far its been about a month that ive had this on my truck and I have no real complaints as of yet.

I followed the video - which was a great help! Removed my original Ford marked part but there was no bushing as described in the video. Is the bushing necessary? Everything seems snug and functional.
Tony M September 8, 2017
Im not sure if its necessary but if everything is snug and it works go with it!
Lori K September 8, 2017
It should be fine. If not just put a thin washer to hold it tight.
Sareta F September 8, 2017
Sorry, it has been a couple years since I installed mine and dont remember is had a a bushing or not.
Stuart J September 8, 2017
Some applications insist on having a bushing, while others do not. If your vehicle does not have a bushing and the part fits snug you are OK to proceed. If there is any play it is recommended to purchase a bushing for complete safe repair.
Alex P September 8, 2017
Mine had a bushing, but the only thing that did was snug it up. Mine was a little loose without it. If it is snug, you should be fine. Test it out, if it works, I wouldnt worry about it.
Kevin C September 8, 2017
Honestly, I dont remember.
