Dont know about hb, but low has a template on their web site that you can print and cut out. I did this when I flush mounted a hds 8 on my 09 cougar ftd. Had to rout out the bottom left corner a tad with a dremel but it fit and looks just fine.Last edited by KyCatFan on November 2nd, 2011, 1:57 am, edited 1 time in total.
