I just acquired a pair of L15s that are missing the grill logos. Do these take the logos WITHOUT the pin on the back (i.e., the ones that are attached with velcro tape)?

Can anybody give me some tips on how to properly go about attaching the logos (when I find some)? I see there are some on Ebay that have the pins on the backside; would it be sacrilege to get these, then grind off the pins and use them?

The only other JBL grill logos I'm familiar with are the ones from my L100s, which have no pins and are affixed with velcro.
