Replacement Toyota RAV4 roof rack screws from crossbars purchased in July 2021. The user manual for these crossbars says it's for model year 2013 and later. I broke one of the screws when trying to get it tighter, and Toyota tells me they don't sell replacements!! After scouring the Internet I cannot find replacement screws anywhere. So my only option is to buy a whole new set of crossbars. I figured I would sell the remaining three perfectly good screws in hopes of saving someone else this hassle... And recouping some of my costs. I would have gladly paid $50 for a replacement if I had found one. These screws are gently used.  Thanks for reading!
