Hello Wiluven, Well, I know this is almost 2 years later after your original post looking for this seemingly impossible to find clips, but I figured you'd appreciate this late reply if you haven't yet found a solution. I too have the same type of "false front clips' and they are breaking left and right. Needless to say it is a real pain since I had been unable to find EXACT replacements. Fortunately after a couple of hours of googling research I am excited to say that I have found a dealer for the elusive part. The link below is to the web page where you can order these. The only downside, if you call it that is that you must order a minimum of 100 pairs of these. But its only $29 and as easily as these seem to break, I have a feeling I will need them in the coming years.
Anyhow here is the link, good luck. Would love for you to reply to let me know if this was helpful or if you already changed all of your clips to a different easier to replace type.
