stupid mirror removal question

[streetracer101]

I have a dumb question. I have an '04 620ie and am trying to remove the mirrors b/c i got bar end mirrors. I cant get the right one off to save my life. before I go and get a breaker bar tomorrow can someone please tell me if its reverse or standard thread that way I dont end up tightening it up more then it already is. ps i already put penetrating lube and that didnt do the trick. thanks

the right mirror, with notches in the nut is indeed a reverse thread
