I bought 45428 26 thinking it would fit as it looks almost identical to 45189 6 but it is not. Can you let me know what is the correct replacement part number.

Thank You

The new version of this lock requires new keepers in order to function, since it's not compatible with the old ones. See our 38-276 and 38-277.
