20" Drawer Slides: Not Self-Closing (Mooney's Bay)

• These two side-mount drawer slides are well-used (~20 years) but very clean and still functional, except for one of the soft close mechanisms;
• One mechanism recently broke (see image), so it no longer pulls the drawer gently shut in the final inches of travel;
• Might be suitable for a seldom-used utility drawer, hamper, etc., but was no longer appropriate in our kitchen;
• Length: 20", full extension to 40";
• Standard-Duty (100 lbs), as far as I recall;
• Accuride replacement part might exist, but might be hard-to-find if needed;
