Hello, I'm in a months long process to replace a failed unigrass 22.5" drawer slide set on one drawer. Cabinet depth is either 22 3/4" or 23 1/2" (see photo). Drawer box is 22" to the back of the faceplate.
The challenge has been to find replacement slides that can mount to the drawer box properly. My drawer has a bottom piece of wood where each replacement slide I have tried and returned has the screw holes going in the space between bottom piece and drawer side (see other photo). Most likely this would split the drawer.
Any thoughts and help would be appreciated. Trying to get our drawer back to working order.
