Off to a good start Travis, just an idea that you might use if your making a hobby stock out of the Chevelle you might make it a lower ride height, you might also consider about removing the grill area and replacing it with a bar connecting both ends to the bumper and running it across where the grille would be.
Also take in consideration that hobby stocks have the headlights and tailights removed. I've also seen some hobby stocks that used to run here at the local dirt tracks around the Dallas area with the door handles on or off.
Depending on how you want to build your's, I'm sure it will look race ready when you get it done can't wait to see it finished.
Hope these ideas might help you out.
Good luck with your's...
