Hey just wanted to pass on a great deal I just got for a new set of NNBS GM tow mirrors. GM part number 19202235 which are heated, power, and have the turn signal in the glass. I got them through Amazon via IAMGMPARTS.COM shipped to my door for $321. I will update this as soon as they land on my door and I get them installed. Check IAMGMPARTS.COM on Amazon if you guys need a set. This was the lowest price I could find GM ones for.
