Motorola T720 T721 rubber back plug

hey, all. if anyone has an extra plug which inserts into the back of
these phones, please email me if you'd like to sell it for a modest
price. i'd be happy to give you a few bucks. i lost mine somehow and
am quite frankly so OCD that i'd like to replace it. this is the plug
that fits into the back above the battery door right next to the
antenna stub base. thanks.
