im not sure where this is supposed to go but, im tryin to remove the heater and ac box in the engine compartment, i took all the visible bolts out that hold it on and i can move it around but it seems there is a hidden bolt holding it in place, wehre is this bolt located? thanks

 

There's about 2 or 3 of em across the bottom on the interior side. At least 1 is under the edge of the carpet.

 

thanks alot
