Quality Cabinet plastic bracket for drawer

Hi,

Quality Cabinets recommended I check your website for a discontinued plastic bracket for a soft/self closing drawer in our laundry room (please see the attached photo). The bracket is located underneath the drawer on the left side and engages the sliding guide. The cabinets were installed in our house when it was built in 2008. Please let me know if you have the part in stock and how to go about getting one. If not do you know where I find it?

Thank you,
Matthew
