I recently bought some Panasonic RP-HJE70 and one of the wax guards sort of caved in. I asked and someone said that the Shure e2c wax guards were also 5mm, but really those are closer to 4mm and don't fit very well (will probably cave in very soon. Any suggestions? Anyone know how I might...

I was cleaning my panasonic rp-hje70s today and noticed that the wax guard is about to fall off. It's a 5mm opening, and I'm wondering what others (if any) would work as a replacement? Anyone know how many mm the shures are?

I can't seem to find an answer anywhere. I lost a medium sleeve for my MD33s and don't really want to pay $10+sh for a new full set from audiocubes. Do the sleeves from the 51/71 fit the MD33? And while I'm at it, if you have Sharp mediums to trade, I've got brand new small/larges.
