GM 22755704 Rubber Hood Stop Bumpers for Chevrolet Silverado GMC Sierra Yukon 2014-2020.  I do not know if these are OE pieces or aftermarket. I purchased 4 and used one of these to replace the missing one on my truck - pictured in this listing. It was an exact match to the OE one shown in the same photo and fit perfectly. I'm saving one and selling the other 2 in this listing.

You will receive the actual items pictured in the first photo.

To install, turn 90 degrees and insert, then turn back 90 degrees to final position. See  photos for application. 

Please ask any questions before purchase.  Item will ship as soon as payment is received. Coming directly from me in the US.  Be careful, other auctions are shipped from China and take many days/weeks to arrive.
