Amazon has no brains when it comes to packing the will either wrap a pet rock like its a fragile Xmax ornament or throw a fragile Crystal wine glass in a huge box with a small sheet of brown paper, And if you complain about to many damaged items they will threaten you with canceling your account!! with no refund of any gift card balance !!!!!!!!!!!! I had a $1200.00 camera lens with no protection it weighed over 6 lbs tear a hole in the box and get lost in transit and amazon sent me a email that they were shutting my account down and i would loose the $500 gift card balance, there excuse? I complained to much about damages to my orders some lost like the lens **Q: 2004 chevy silverado z71 crew cab 5.3L do you know how many i need and do you know if is the same or diferent part number** A: You need two and the wiring harness. DO NOT BUY THESE EXCEPT FROM CHEVY DEALER!!!! THESE ARE CHEAP ASS KNICK OFFS THAT DO NOT......REPEAT.....DO NOT WORK.......spend the extra money or you will do the job twice. Second time with factory parts.......trust me!!! **Q: Is this item made in México?** A: Made in Mexico or not (mine weren't labeled) these failed. I'm trying third set from brick and mortar store.
