Refined the lower grill block to be much easier to remove or apply in less than a minute. The lower grill screen is now ziptied to the OEM air dam upper slat so the screen won't need to be held in place when removing/applying the grill block.

I'll be building some ducting so the dual transmission coolers git the air directed through them instead of being washed off to the sides.
The main upper grill block is currently at 67% and I can easily change the configuration to 50%, 33%, or 0% just by removing the velcro zipties and the associated PVC pipe.
