Towing Mirrows

[ARARAR]

Does anyone know if the new stock towing mirrows that fold out are inter-changeable; that is, just the glass portion? I love my 04. 5 but those mirrows, the wide angle portion just seems to be in the wrong place. Everytime I look out the right side the my eyes seem to focus on the wide angle view, which usually isn't my first concern and takes way more concentration. I'd rather that portion be on the inside and they would still serve a good purpose when folded out while towing; they would be on outer upper portion of the mirrow.
