Wow, that's just like the car I'm building now, same seats and everything. If you want a grill like that, you'll have to make it, combine a 70-72 stock grill, with a Grabber grill. It's been done, and posted on here a few times.
I've seen that video a while back, that car is beautiful!! I actually thought about changing to those wheels too! I had 2 broken grills like Dave mentioned and I was considering doing that as well. It does look great.
