Returning the mirrors would result in a some-what net loss, so I'm going to bend them to my will and make them work how I want. This leaves me with the blanking panel for the passenger side to make that whole thing nice and removable.
Also, the grill finally came in, so new toys all around! (also fun what my fiance's "what do you mean, 'new grill'?" reaction)
