Just finished this install. Ordered a 2007 Trailblazer part# DCA883459596 off of Ebay for $30.00. Basically only done this due to my $100 blendmount 9500IX passport radar detector mirror mount that came out of my 2006 Tahoe and wouldn't fit the G8 mirror due to the flip button on the bottom. $30 mirror or another $100 mount, hummmm.... It was plug and play, easy.
