Reply to Slider caps

Hi guys

So I've been believeing about what I want to put on my Remote 25SL to mod it for my liking. I have decided I want to use the slider caps (not faders) from the black SE edition (with some creative hacking away at plastic with some sort of sharp object and some heavy duty glue). Any ideas where I can get only those? I'm going to get the pack for the knobs and maybe replace the faders on mine anyways

but where can I get those slider caps only? Any ideas?
