BTW, the hole on the latch appears to be too small to allow the hood to close... the main difficulty in making these panels is getting the cutout to match up to both the hood AND the latch mechanism.
I have a final prototype panel from the GB lying around that will give you the NA and TT dimensions for the panel; that will save you ALOT of effort in prototyping. I took around 4 tries (very costly on a CNC machine) just to get the dimensions down to within 1/8". Shoot me an email if you want to borrow it.
