i went to put in the AC delete box i got and it seems that only 2 (maybe 3) holes line up?? is this normal, do i need to drill new holes or something?

in the pic...green circles r the ones that match, the red is the one that i'm not sure on

 

You shouldn't have to drill new holes afaik, when I deleted the A/C on my '88 bird I didn't have to drill any.
there should be holes on the firewall that will line up with your heater box.
the A/C system uses different holes than the heater and on all the cars I have seen both are provided.
However, I have heard of a few camaros not having all the holes for the heater box on occasion, so I imagine a few Birds may have the same issue.
Some members on this board have had to drill new holes but typically they used S-10 boxes.
