Lubavitcher Rebbe and ear Piercing

I received the following email:

Rabbi Bechhofer,

I've been listening to your very interesting Shiurim on Chabad on Torahanytime and from http://www.sumseqfiles.com/shiurim/. You mentioned that the Rebbe was against ear piercing and that Chabad interestingly did not follow his Psak. I noticed on the Chabadtalk forum they site this piece from the Rebbe - http://www.hebrewbooks.org/pdfpager.aspx?req=14943&st=&pgnum=580&hilite= where he's Matir and they make no mention of any issur. I was curious if you saw his Psak issur in print or heard it?

Thanks,

I would like to concede the point, that I was in error, and that the Rebbe in fact seems to have preferred pierced ears over clip-on earrings, as per the image above. My only "limud zechus" on myself is that the Rebbe held the issue worthy of a she'eilas chacham!

Worthy of note is the reference to the Radal, as per the other image above!
