I'll be the first James. I recently completed this one.
Yep, as you say, most are two tone. The kit if done without alterations should come togather nicely. My problem was I mated the back half of the '66 Nova tubbed chassis to the front of the kit chassis and had issues. Would never do it again...was too much for my skill level. As you can tell, these are not the kit wheels and tires, and the hood.
Anyway, good luck with it, you'll do fine.
