I’m looking but all I can find are the threaded ones. I’m looking for some clear white snap-ins from my SE. Kind of like the PS 14 KN. Any help would be appreciated. Also, if you could give me some tips on how to fit the threaded ones into the SE in case I can’t find a snap-in, that would be helpful too. I’m afraid that if I buy them, I’ll mess it up when I file 'em down.
