    Fire wall is a little different under the heat and A/C boxes but you can do a little cutting and a little patching and make it work. Other than that they are the same...well almost. Non A/C trucks have freash air flaps in the kick pannels. You can just block those off and run the A/C duct work and A/C dash Bezel.
    Bolting to the frame is no problem between a 77 and 76. Where you get into trouble is putting a 78 up body on a 77 down frame. You can put a 77 down body on a 78 up frame by making a different cab suport behind the front seats easy enough but the 78 up rear foot well will hit the frame trying to go the other way.
