Mach 1 2003-04 Shaker Hood pass-through dimension

[MLCrisis]

Hey there Machers!

I am looking for the dimension of the hole in the hood of a 2003-4 Mach 1 which the scoop passes through. I looked around online but just couldn't seem to find the answer. Could someone take 30 seconds and get a rough figure?

Thanks in advance!

17 7/8" (N,S) X 14 7/8" (E,W) at it's widest point in the middle.
