Boss BCB-60 pedalboard issue

[invader3k]

Hey all. I've had the above pedalboard for probably 6 or 7 years already. Recently, one of the sliding "locks" (which are made out of plastic) has started to severely crack, to the point where it will be useless shortly. Does anyone know where I might be able to get replacement ones from? It would be a shame to get rid of this otherwise good and functional pedalboard just because one of the sliders is cracked.

Thanks in advance for any help.
