carmy

It's infuriating. I bought 6mm-1x20 but those didn't work. I dont know if its because the plastic screws broke off inside and I had to drill them out and it affected the threads or if its just the wrong size screw. I have a 2009 Camry and a 2004 Camry. I'd really appreciate any help as I'm going nuts and might just buy some stainless self tapping screws and go to town, lol. Thank you!
