No markings on anything except L and R. Cannot match dimensions to anything I find online. Overall dimensions are: 2.5" H x 1.5" W x 3" L. Channel outside dimensions are: 1.2" H x 0.5" W. Channel inside dimensions are: 1" H x 0.4" W.

Our 32-119 rear drawer bracket might work with your tracks. The track opening on our bracket is 31/32" X 7/16". Does that match what you have?
