Heater box Issues Non AC

[SFEBODY]

I have a 70 Challenger that the heater box is hanging down and the gasket on the passenger side is about 7/16 inch from touching.
What I mean after installing it, it will not fit flush at the top of the car metal. It hangs almost like the weight of it pulls it down away from the cowl.
Picture Heater 1 up tight with it propped up. Picture 2 without anything holding it up.

I tightened the 3 nuts buy the heater blower motor while bracing up the box on they inside but it still hangs down  when I pull the brace out.

Any suggestion???

There is A J-hook missing! straight up up from the lever and cable. the hook go's inside and A bolt go's through the hole. leave it loose, install heater box and then tighten up the hook. A factory service manual will show it, if you don't have one I would suggest getting one. they have them on C-D so you don't have to be as careful as with A book. good luck and happy 4th of July.   Mark.

   @SFEBODY  that is all you are missing and that will solve your problem.  That "J" hook is often missing.

You can make your own like @Bullitt-  did or they are reproduced.  @MoparDave  sells them and will give you the E-Bodies.org discount.

Didn't notice it wasn't an OE style J-hook ..Not my doings, just a picture I found on the www 
I suppose that would work though
