replace part for ACME bottom guide

Need a replacement part for ACME bottom guide for a sliding closet door. I'm showing a picture of bottom guide with nylon piece that drops into tracking groove mounted to floor.

Two other pics show the bracket that nylon piece is mounted on (attached to backside of closet door), but is missing the nylon piece.

The latter two pics have a bunch of patent numbers and perhaps ACME's original part number?

Is your 23-026 a compatible part? It would have to install on the inside corner of the sliding closet door. Please advise. Thanks.
