The conversion kit includes a new set of outside guides, adaptors, and a sheet of instructions regarding the removal of the old guides and the installation of the new units. They will replace the left and right plastic adaptors. The kit includes hardware for one drawer or sliding shelf. For 21" deep cabinets only. Available in white.
Note: Merillat discontinued the drawer slide brackets. The replacement guides in the conversion kit can be used as a substitute to these older slide brackets.

I couldn't get the plastic brackets installed in the back of the cabinet but the rails made an allowance for that with the ability to screw the bracket into the cabinet. The biggest drawback was it took 18 days to receive these brackets so plan accordingly.
