I am still a bit confused.. So with the risk be being found stupid I still have some questions!
Could there be a difference between 67 and 68 Firebirds concerning the heater core? Is the motor separted from the case in 68's and in one piece in 67's?
On Davids pics it shows that the case has 2 bolts on the outer side, underneath the front fender, as seen on the pic A below. Bolt number 6&7 in pic A are for the motor right --> do they stay in place? (Bolts "M" in pic E). So then you only take out bolts nr. 1-5 in pic A (or the red "C" bolts in pic E). Is that correct?

When I release those bolts, I just pull on the entire Case and duct system from underneath the dash, and it comes off right?

How come on the drawing (pic C) there are 3 bolts shown (bolts A, B, C), but on the pics there are only 2 bolts on the outside?
A (on pic C) seems like bolt I (on pic D), and C = V (pics C & D compaired), but where is bolt B from pic C gone in D? Sorry for the confusing letters and numbers... Bolts A, B and C in pic C, were are they in pic A & D? Is it because 67 and 68 is different?

David, another stupid question (remember english is not my first language... Try doing this in dutch!), the inner fender brace, were is it located? Can you see it in pic B? Does the hood hinge come off...?

Thanx for all the info. I'm not as much of a garage head as some of you guys and just like to be prepared...
