Need product 32-018 (?) for 1" slide and at least 4" long

Hello, I need to replace the rear mount drawer sockets on many of my cabinets. They are cheap and do not hold up against my children. I measured and the opening for the slide needs to be 1" and the socket needs to be at least 4" long. Can you please guide me to the right one. I ordered replacements but the are slightly too large and my drawers aren't flush to the cabinet.

Please help,
Maria
