Hi everyone. I have a 2012 Silverado with an "OEM" tonneau cover. The part number of tonneau is 22870555. https://www.gmpartsgiant.com/parts/gm-cover-22870555.html This is the part # for the entire assembly, there is no breakdown ( That I can find) of the individual parts. The actual lock for the cover is broken. 2 different locksmiths told me they couldn't help and I need to find the part myself. All GM parts places that I have tried have it listed as discontinued ( no surprise here) I believe what I need to do is find the original manufacturer to see if they can help. My local GM dealership said they can't help because they have n o I formation more than I have. My local truck accessory place wasn't able to help. Lastly. I called the largest truck dealer around to see if they could help. Their sales guys were Johnny's on the spot but I could not get their parts people to return my contact. Can anyone suggest a way to find the manufacturer or a replacement lock? Sparky
