Arturia keylab 49 parts

Hi, I am actually reparing a Arturia keylab 49 midi controller and I am looking for the base where you fix the keys (see the link for pictures). One of the plastic parts that retain the key in position is broken and I do not have it anymore to glue it back on the frame, so I’m looking to replace it. It may come with or without the aftertouch strip. Also, if you have a DIY trick to replace that part so I dont have to replace the whole thing, it would be very cool! Thanks!
