Whoa, Tim! Is that a subtle hint? Because, honestly, I didn't notice the naca ducts. But now that you pointed them out, they stick out like a sore thumb! I will absolutely be adding them! It just shows what a good eye for detail you have.
I stole the U-joints for the half shafts from a Corvette rear end. I polished up the white metal oil tank that came with the kit and dipped it in Future to try to keep it from tarnishing over time. I also put some bungs in it so I can add oil lines later.
