Congrats on COTW!
Love what you've done. Saw what you're doing on the brake ducts -- awesome.
As a possible alternative:
I'm using the ZL1 version. If you get the lower radiator shroud, it has the blocks removed.
Here is some info (from my build thread) on the ZL1 ducts I'm using for my bumper conversion with part numbers and prices:

Again, congrats on COTW and love reading what you've done. I found the pan removal option super -- I did get CFD's parts just in case, but really like how you did it. Thanks for sharing!
