head unit...

[72hotrod]

The radios I have installed have a stud or threaded hole in the back end for a support strap. Get one with holes from a car radio installer or something generic from some hardware or auto parts store. Set the unit in the dash, attach the strap to it just snug, find some solid structure under the dash that you can screw the strap to, bend it just enough to reach(straighter is better),mark the location for the screw (be sure the unit is straight/level). Remove the unit, attach the strap where you marked under the dash with a screw, re-install the unit and connect the strap to it. Just look at everything carefully and use common sense. I really hate getting under the dash 'cause I'm usually in some contortionist pose (like upside down) where my neck is straining to hold up my fat head, and all the blood in me is in the wrong place. And under the dash is tight, making me cuss from frustration and claustrophobia. So, grit your teeth and bare it so you can get it done and start enjoying the tunes as you cruise!
